Procedure

10 g (0.04 mole) of 2-(4-chlorobenzylidene)-5,5-dimethycyclohexanone prepared according to Example 1(a) were dissolved in 50 ml dichloromethane and cooled to 5-10° C. Bromine (6.4 g, 0.04 mole) was added over 5 minutes to give 2-bromo-2-(α-bromo-4-chlorobenzyl-5,5-dimethylcyclohexanone in solution.
