Irradiation of 3-aza-1,2,2,4,4-pentaphenylbut-3-en-1-one in t-butanol gives two photoproducts in good yield.The formation of these products is interpreted in terms of 1,3- or 1,5-benzoyl migration.This is the first report of an acyl migration from a saturated carbon into a substituent phenyl group.

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.
