Procedure

A tetrahydrofuran solution of 3,7-dimethyloctylmagnesium bromide was prepared from 6.64 g (0.03 mol) of 3,7-dimethyloctyl bromide, 0.73 g of metalic magnesium, 40 ml of tetrahydrofuran and 3 droplets of ethylene dibromide as a reaction initiator in a similar manner to that of Example 1. 4.08 g (0.03 mol) of anhydrous zinc chloride was added to the solution, while keeping the solution at 10° C. The obtained mixture was stirred for one hour to give a cloudy tetrahydrofuran solution of 3,7-dimethyloctylzinc chloride.
