Abstract
The synthesis of 2,2-diphenyl- and 2,2-bis(p-chlorophenyl)-1,4,4-triphenyl-3-azabut-3-en-1-one is described. The photochemical reactivity of these compounds is described and interpreted in terms of 1,5-benzoyl migration, the terminus of which rearrangement is a phenyl ring. This type of reactivity is novel for β,γ-unsaturated systems.Keywords
