Preparation of Primary Amines by the Copper(I) Catalyzed Reaction of 4,4′-Bis(trifluoromethyl)benzophenone<i>O</i>-Methylsulfonyloxime and Alkyl Grignard Reagents
Primaryamines are prepared by the reaction of 4,4′-bis(trifluoromethyl)benzophenone O-methylsulfonyloxime and alkyl Grignard reagents in the presence of a catalytic amount of CuCN•2LiCl and the successive acid hydrolysis of the resulting N-alkylimine derivatives.
