N-Arylimines and 1-methyl-1-phenylhydrazones of diaryl ketones were prepared, their yields being affected by the electronic and positional effects of substituents of reagent and substrate. Direct preparation of some anils of xanthone and its 1-methyl-1-phenylhydrazone was achieved by use of the corresponding iminodimagnesium reagents.
