Product 1

HCID 127659741-Bromo-4-[(4-chlorophenyl)sulfanyl]-3,3-dimethylbutan-2-oneYield 99%

Procedure

64 g (0.4 mol) of bromine are added slowly at room temperature to 97 g (0.4 mol) of 1-(4-chlorophenylsulphenyl)-2,2-dimethylbutan-3-one. The reaction mixture is worked up as in Example 1. 127 g (99% of theory) of 1-bromo-4-(4-chlorophenylsulphenyl)-3,3-dimethylbutan-2-one are obtained as a viscous oil. ##STR119##
