Method for producing triarylorganoborates

Abstract

The invention relates to a process for preparing triaryl organo borates proceeding from organoboronic esters in the presence of an n-valent cation 1/n K.sup.n+, comprising the anhydrous workup of the reaction mixture and the use of the triaryl organoborates obtained as co-initiator in photopolymer formulations, holographic media and holograms.

(49) Preparation Method a1) for Triaryl Organoborates with Cations of Valency n=1

(50) 10.0 mmol of the specified boronic ester (I; R.sup.1), 30.0 mmol of magnesium turnings and 10.0 mmol of the salt (II) were suspended in a mixture of 3.40 g of anhydrous toluene and 0.73 g of anhydrous tetrahydrofuran in a dry four-neck flask with a mechanical stirrer, thermometer, metal condenser and pressure-equalized dropping funnel under a nitrogen atmosphere, and stirred vigorously for 30 min. The appropriate haloaromatic (III, R.sup.4) was added to this solution, at first in undiluted form, until the onset of exothermicity signals the start of the reaction. The remaining total amount of 30.6 mmol of haloaromatic was diluted with 10.0 g of anhydrous toluene and 10.0 g of anhydrous tetrahydrofuran and added dropwise at such a rate that the internal temperature does not exceed 45? C. On completion of addition, the reaction mixture was heated at reflux for 1 h or until the dissolution of the magnesium was complete. The reaction mixture was cooled to room temperature and 100 g of 1,4-dioxane were added dropwise. After standing overnight, the voluminous crystals that had precipitated out were filtered off, the organic phase was concentrated to dryness and the residue was recrystallized from 100 ml of i-propanol. Examples 15, 18, 20 and 27 and 46-52 were isolated without recrystallization as oils with a purity of >90%. The isolated yield for Example 1 that was prepared by this method was 2.87 g (72% of theory), whereas Example 1 prepared according to DE 198 50 139 A1 was obtained in a yield of 47% of theory.

(55) Preparation Method b1) for Triaryl Organoborates with Cations of Valency n=2

(56) 10.0 mmol of the specified boronic ester (I; R.sup.1), 30.0 mmol of magnesium turnings and 5.0 mmol of the salt (II) were suspended in a mixture of 3.40 g of anhydrous toluene and 0.73 g of anhydrous tetrahydrofuran in a dry four-neck flask with a mechanical stirrer, thermometer, metal condenser and pressure-equalized dropping funnel under a nitrogen atmosphere, and stirred vigorously for 30 min. The appropriate haloaromatic (III, R.sup.4) was added to this solution, at first in undiluted form, until the onset of exothermicity signals the start of the reaction. The remaining total amount of 30.6 mmol of haloaromatic was diluted with 10.0 g of anhydrous toluene and 10.0 g of anhydrous tetrahydrofuran and added dropwise at such a rate that the internal temperature does not exceed 45? C. On completion of addition, the reaction mixture was heated at reflux for 1 h or until the dissolution of the magnesium was complete. The reaction mixture was cooled to room temperature and 100 g of 1,4-dioxane were added dropwise. After standing overnight, the voluminous crystals that had precipitated out were filtered off, the organic phase was concentrated to dryness and the residue was recrystallized from 100 ml of i-propanol.

(66) Example Medium I

(67) 3.38 g of the polyol component 1 were mixed with 0.010 g of Example 1, 2.00 g of urethane acrylate 1, 2.00 g of urethane acrylate 2, 1.50 g of additive 1, 0.10 g of triaryl alkyl borate 1 of formula (IV), 0.010 g of dye 1 and 0.35 g of N-ethylpyrrolidone at 60? C., so as to obtain a clear solution. Subsequently, the mixture was cooled down to 30? C., 0.65 g of Desmodur.sup.+ N3900 was added and the mixture was mixed again. Finally, 0.01 g of Fomrez UL 28 was added and the mixture was mixed briefly again. The fluid mass obtained was then applied to a glass plate and covered thereon with a second glass plate. This specimen was left to stand at room temperature for 12 hours and hardened.

(68) Example Medium II-XX

(69) The procedure was as in Example medium I, except using 0.10 g of the specified triaryl organoborate of formula (IV) rather than 0.10 g of triaryl organoborate 1.
