The photolysis of Schneider's 1-phenyliminopyridinium ylides

Abstract

Photolysis of the pyridinium ylides (4) and (5) produces, besides high yields of aniline and (8) and (9) respectively, the additional products (10)[from (4) in benzene] and (12)[from (5) in diethylamine] which suggest a phenyl nitrene intermediate in these reactions.
