A process for the manufacture of a terphenyl compound [compound (T), herein after] of formula (T): wherein each of R and R, equal to or different from each other, are selected from the group consisting of halogen, alkyl, aryl, ether, thioether, ester, amide, imide, alkali or alkaline earth metal sulfonate, alkyl sulfonate, alkali or alkaline earth metal phosphonate, alkyl phosphonate, amine and quaternary ammonium; each of j and k, equal to or different from each other, are zero or are an integer from 1 to 4, including the steps of (i) reacting at least one organozinc compound of formula (I) with at least one dihalocompound of formula (II) in the presence of a catalyst compound; wherein Y is selected from the group consisting of a chloride, a bromide, an iodide, an alkanesulfonate or a fluoroalkanesulfonate anion, R2 is selected from selected from the group consisting of C.sub.1-C.sub.10-alkyl, C.sub.3-C.sub.10-cycloalkyl, C.sub.1-C.sub.10-halooalkyl and C.sub.3-C.sub.10 halocyclo alkyl, each of Z, equal to or different from each other, are selected from the group consisting of a chloride, a bromide, an iodide, an alkanesulfonate or a fluoroalkanesulfonate anion; (ii) a Bayer-Villiger oxidation and (iii) hydrolysis or alcoholysis.

Provided is a method for preparing a cannabis oil composition, the method comprising the steps of eluting cannabinoids from dried cannabis plant material with a solvent to produce an eluate, filtering the eluate with a series of filters to produce a filtrate, evaporating the solvent by condensing from the filtrate with a distiller to extract the distillate, and purging the distillate via fractional distillation to remove residual solvent, thereby producing a cannabis extract. The method also includes the steps of performing a redox reaction of the cannabis extract for the complete removal of the water for creating CBN (Cannabinol) of various percentages depending on the timeframe in which the redox reaction is performed; and combining the cannabis extract with an essential oil or a carrier oil to produce the cannabis oil composition.
