Photochemical reactions of 2,3-dichloro-1,4-naphthoquinone with 1,1-diarylethylenes or the related electron-rich alkenes have been investigated by steady-state photoreactions, flash photolysis, and kinetic analyses based on the Stern-Volmer experiment and concentration dependence of quantum yields; there is reasonable agreement between them.In acetonitrile a radical ion pair composed of a quinone radical anion and a 1,1-diarylethylene radical cation was observed, while no intermediate was observed in benzene.Dimerization products derived from radical cations were obtained only in the photoreaction of quinone with 1,1-bis(4-methoxyphenyl)ethylene.
REACTION MECHANISM OF ONE-POT SYNTHESIS OF POLYCYCLIC QUINONES - DIRECT EVIDENCE OF PHOTO-INDUCED ELECTRON TRANSFER PROCESS

Photo-induced cyclocondensation of 2,3-disubstituted 1,4-naphthoquinone (substituents; halogen atom or methoxy group) with 1,1-diarylethylene provides us a powerful one-pot synthetic method of polycyclic quinones.Involvement of electron transfer process i
