The most preferable bases are hexamethyldisilazane salts [metal bis(trimethylsilyl)amides] represented by the Formula MHMDS, wherein M is an alkali metal, such as potassium or lithium. Process of deprotonation or contacting together suitable reagents could conducted in many polar or nonpolar solvents. Preferably toluene is used as a solvent. In the following step, the CAAC carbene formed is contacted with first generation ruthenium complex containing in its structure two phosphine-type ligands.
[0074] It has been shown, that the main product of this reaction is a second generation complex containing two CAAC ligands. In the TLC analysis one could observe also small amounts of the other second generation complex, which most probably contains one CAAC ligand and one phosphine ligand, Scheme 1 and 2.
##STR00028##
[0075] The last process step is the addition of benzylidene ligand 4 to the mixture of unknown proportion of major and minor intermediates 5, in the presence of phosphine ligand scavenger and/or CAAC ligand scavenger (Scheme 2). Scheme 2 shows only the proposed course of 16-electrone ruthenium complex formation without detailed analysis of the metathesis process mechanism. Preferably, as a benzylidene ligand 2-isopropoxypropenylbenzene derivatives are used. It appeared that the preferable phosphine and/or CAAC ligand scavengers were copper(I) salts, including CuCl. Reactions shown in the Scheme 1 and 2 were conducted in a single reaction vessel without isolation of the intermediates (Embodiments !-XIV).
[0076] To confirm that the intermediate compound 5 takes part actively in the preparation process of the precatalysts represented by the Formula 1, the previous one-pot type process was divided into two independent reaction parts, (a) and (b) in the Scheme 3. Ruthenium complexes represented by the general formula 5 were isolated and characterised with the NMR and MS analysis, confirming lack of phosphine ligand in the structure and presence of the two CAAC ligands. It has been shown, that compounds represented by the structure 5 in the reaction with benzylidene ligand 4 in the presence of CAAC ligand scavenger provide compounds represented by the Formula 1. Reactions for individual steps were shown in the Scheme 3 (part (a) in Embodiments XV, XVI and XVIII and part (b) in Embodiments XVII and XIX). Moreover, the inventors decided to check, whether intermediate compounds represented by the general formula 5 are active precatalysts in the olefin metathesis, what was shown in the Example XXII.

[0171] Application of Precatalysts 1a-1j in Ethenolysis Reactions of Fatty Acid Methyl Esters which were Obtained by Rapeseed Oil Transesterification (MOR).
##STR00052##
[0172] To the reaction, a mixture of fatty acid methyl esters which were obtained by rapeseed oil transesterification (MOR), was used, composed of: about 61% methyl oleate, about 21% linoleic acid methyl ester, about 10% ?-linolenic acid ester, about 7% saturated fatty acid methyl esters including about 4% methyl palmitate and about 2% methyl stearate.
[0173] To degassed MOR (610 g) cooled to 0? C. a solution of catalyst (0.052 mmol) in dry deoxygenated toluene (5 mL) was added. The mixture was vacuum-pumped to an autoclave and stirred for 2 hours at 30? C. at 10 bar of ethylene. After 2 hours the reaction was quenched and to the reaction mixture 6 mL 0.1 M solution of SnachCat [CAS: 51641-96-4] was added to deactivate the catalyst.
##STR00053##
[0174] The samples were analyzed using gas chromatography. The conversion was determined using methyl palmitate as an internal standard.
[0175] Reaction mixtures obtained in reactions catalysed with 1d and 1e after filtration through short pad of silica gel were distilled under reduced pressure, giving 173 g and 179 g of 9-decenoic acid methyl ester (9-DAME), respectively.

[0217] Preparation Method of Intermediate 5 g and Minor Compound 6g from Precursor M1 and CAAC Salt 3ag.
##STR00060##
[0218] To salt 3ag (1.99 g, 6.0 mmol, 3 molar equivalents) dry deoxygenated toluene (14 mL) was added in argon atmosphere. The mixture was heated to 80? C. and solution of LiHMDS in toluene (1 M, 6.0 mL, 6.0 mmol, 3 molar equivalents) was added. After 1 minute solid complex M1 (1.85 g, 2.0 mmol, 1 molar equivalent) was added. After 30 minutes the mixture was cooled down to the room temperature. Triethylamine (2 mL) was added and filtrated through a short pad of silica gel (deactivated with triethylamine), which was washed with 50 mL toluene/triethylamine mixture (95:5 v/v). Solvents were evaporated under reduced pressure. Crude products 5 g and 6 g were isolated by column chromatography on silica gel (deactivated with triethylamine; eluent: from cyclohexane/triethylamine (95:5 v/v) to cyclohexane/ethyl acetate/triethylamine (90:5:5 v/v/v)). Two red brown fractions were collected and concentrated to dryness. First fraction residue was dissolved in n-pentane. Solvent was evaporated to 25% of its original amount-precipitate formed during evaporation was filtrated off, washed with a minimal amount of cold n-pentane and dried under high vacuum giving an orange brown crystalline solid-compound 6g (0.270 g, 15%). Second fraction residue was dissolved in n-pentane. Solvent was evaporated to 25% of its original amount-precipitate formed during evaporation was filtrated off, washed with a minimal amount of cold n-pentane and dried under high vacuum giving an orange brown crystalline solid-compound 5g (0.350 g, 21%).

[0266] Application of Precatalysts 5c-5i in Ethenolysis Reactions of Methyl Oleate (MO).
##STR00067##
[0267] To degassed MO (35.0 g, 118 mmol) a catalyst (10 ppm or 5 ppm) solution in dry deoxygenated toluene (100 ?L) was added. The mixture was vacuum-pumped to an autoclave and stirred for 5 hours in a suitable temperature at 10 bar of ethylene. After 5 hours the reaction was quenched and after removal of ethylene from the reactor to the reaction mixture 0.1 mL 0.1 M SnatchCat solution [CAS: 51641-96-4] in methylene chloride was added to deactivate the catalyst. The samples were diluted with methylene chloride and analysed by gas chromatography. The conversions were calculated using residual methyl stearate as an internal standard. The results were summarised in Table 6.
[0268] In order to determine the FID detector response factors to individual components of the reaction mixture a mixture of substrate-methyl oleate (MO), desired reaction products: 1-DECENE and 9-DAME, and reaction by-products OD-9-ENE and DIESTER-C18 diester according to the table below was prepared. The resulting mixture was diluted with toluene to 10 mL and analysed by gas chromatography. The area under the peak (AUP) for each component (mean of seven injections) was divided by the component mass of the analytical sample taking into account its purity and obtaining absolute response factor of a given component Rf. Assuming the response factor of methyl oleate (MO) equal to Rf=1, from the proportions the absolute response factors Rf for remaining components were calculated.

[0269] In the further calculations, the area under the peak of a given component on the chromatogram was converted into percentage in the mixture using response factors calculated above.
[0270] Reaction selectivity (S) was determined from the formula:
S=100?(n.sub.1-DECENE+n.sub.9-DAME)/[(n.sub.1-DECENE+n.sub.9-DAME)+2?(n.sub.OD-9-ENE+n.sub.DIESTER-C18)]
where n is the number of moles

[0315] Preparation Method of Precatalyst 1d without CuCl.
##STR00077##
[0316] To salt 3ab (0.345 g, 1.0 mmol, 2 molar equivalents) dry deoxygenated toluene (4 mL) was added in argon atmosphere. The mixture was heated to 80? C. and solution of LiHMDS in toluene (1 M, 1.0 mL, 1.0 mmol, 2 molar equivalents) was added. After 1 minute solid complex M10 (0.443 g, 0.5 mmol, 1 molar equivalent) was added. After 2 minutes benzylidene ligand 4a (0.176 g, 1.0 mmol, 2.0 molar equivalents) was added. The whole was stirred for 30 minutes at 105? C. and cooled down to the room temperature. The crude product was isolated by column chromatography on silica gel (eluent: toluene). Green fraction was collected and concentrated to dryness. The residue was dissolved in ethyl acetate and evaporated and the residue was washed with isopropanol and dried under high vacuum giving green crystalline solid-precatalyst 1d (0.130 g, 45%).
[0317] Analytical data for product 1d obtained by this method were identical as in Example VII.

[0318] Preparation Method of Precatalyst 1m without CuCl.
##STR00078##
[0319] To salt 3ad (0,407 g, 1.0 mmol, 2 molar equivalents) dry deoxygenated toluene (4 mL) was added in argon atmosphere. The mixture was heated to 80? C. and solution of LiHMDS in toluene (1 M, 1.0 mL, 1.0 mmol, 2 molar equivalents) was added. After 1 minute solid complex M10 (0.443 g, 0.5 mmol, 1 molar equivalent) was added. After 2 minutes benzylidene ligand 4a (0.176 g, 1.0 mmol, 2.0 molar equivalents) was added. The whole was stirred for 30 minutes at 105? C. and cooled down to the room temperature. The crude product was isolated by column chromatography on silica gel (eluent: toluene). Green fraction was collected and concentrated to dryness. The residue was dissolved in methylene chloride and excess of isopropanol was added. Methylene chloride was evaporated under reduced pressure, the resulting precipitate was filtrated off and washed with a small amount of isopropanol. It was dried under high vacuum giving green crystalline solid-precatalyst 1m (0.151 g, 47%). A mixture of A:B isomers=1:4.
[0320] Due to a very complex .sup.1H NMR spectrum only the characteristic benzylidene proton shifts were given: isomer A: singlet 17.88 ppm, isomer B: singlet 16.51 ppm (C.sub.6D.sub.6).

[0321] Preparation Method of Intermediate 5a from First Generation Precursor M10
##STR00079##
[0322] To salt 3aa (10.00 g, 29.0 mmol, 3 molar equivalents) dry deoxygenated toluene (50 mL) was added in argon atmosphere. The mixture was heated to 80? C. and solution of LiHMDS in toluene (1 M, 29.0 mL, 29.0 mmol, 3 molar equivalents) was added. After 1 minute solid complex M10 (8.56 g, 9.66 mmol, 1 molar equivalent) was added. After 5 minutes the mixture was cooled down to the room temperature. Reaction mixture was filtrated through a small amount of silica gel and washed with toluene. The crude product was isolated by column chromatography on silica gel (eluent: ethyl acetate/cyclohexane 1:9 v/v). Red fraction was collected and concentrated to dryness. It was dissolved in n-pentane and slowly concentrated to dryness (the product crystallised during solvent removal). Red crystalline solid was obtainedan intermediate compound 5a (5.02 g, 59%). Comparison with Example XV.
