Phenacylideneaniline was formed by Et3N-catalyzed elimination reaction of the hydroxylamine obtained from silyl enol ether 5a and nitrosobenzene (6). By this method, one-pot procedure was possible for cycloaddition reactions of the related anils. From these reactions, it was revealed that 6 reacted efficiently with a silyl enol ether having a π-donating substituent.
