摘要

Abstract Photoinduced electron-transfer reaction of α-bromomethyl-substituted benzocyclic β- keto esters with tertiary amines was investigated. Debrominated β-keto esters and ring- expanded γ-keto esters were obtained as major products. On the basis of mechanistic experiments it was concluded that these products are formed via a reaction sequence of selective carbon–bromine bond cleavage and subsequent competitive hydrogen ...
