Ozone had no effect on diphenylethyleneimine. The benzoyl derivative was prepared in pyridine by the action of benzoyl chloride. In dilute sodium hydroxide the same reagent formed α-β-diphenyl-β-chloroethylamine. This compound was changed to benzoyl diphenylethyleneimine by heating with alcoholic sodium ethylate. On being heated to 225° diphenylethyleneimine rearranged to benzalbenzylamine. A number of experiments were tried in an attempt to prepare aminoethenes but the results were not conclusive
