Abstract

1-Bromo-3,5-bis(trifluoromethyl)benzene was selectively prepd. by treatment of 1,3-bis(fluoromethyl)benzene with N,N'-dibromo-5,5-dimethylhydantoin in strongly acidic media. A no. of synthetically useful reactions via 3,5-bis(trifluoromethyl)phenylmagnesium, -lithium, and -copper intermediates were accomplished. [on SciFinder (R)]
