Photoinduced Electron-transfer Reaction of Pentafluoroiodobenzene with Alkenes
Autor: Qing-Yun Chen, Zheng-Yu Long, Ping Cao
Publikováno v: Molecules, Vol 2, Iss 1, Pp 11-16 (1997)
Irradiation of pentafluoroiodobenzene and alkenes gave the corresponding adducts. The presence of single electron-transfer scavengers, (p-dinitrobenzene and t-Bu2NO) and the free radical inhibitor (hydroquinone) suppressed the reaction. A photoinduce
