• Reaction of Grignard reagents with aromatic nitriles is potentially a useful route to ketones via the imine. However, in the absence of a catalyst, reaction is generally very slow and gives indifferent yields. In the presence of CuBr, tert-butylmagnesium chloride reacts readily with benzonitrile to give tert-butyl phenyl ketone in 94% yield: J. Org. Chem., 52, 3901 (1987).
