- Process for the preparation of terpenes
-
A terpene compound having the formula (III) is produced by reacting an allylic halide having the formula (I) with a Grignard reagent having the formula (II) in the presence of anhydrous zinc chloride and a copper compound or an organic zinc halide compound having the formula (IV) in the presence of a copper compound, provided that when A-A is C-C, R' is hydrogen and when A-A is C=C, X is chlorine.
