UV-Induced Catalyst-Free Intramolecular Formal Heck Reaction

Publication date: Available online 31 December 2018Source: Journal of Saudi Chemical SocietyAuthor(s): Wangsheng Liu, Dongmei Ma, Hao Guo, Guangxin GuAbstractA catalyst-free intramolecular formal Heck reaction has been developed, affording 9-benzylidene-9H-fluorene derivatives under UV irradiation. This reaction probably proceeds via UV-induced homolytic cleavage of C-I bond, addition of the aryl radical to the alkene moiety, single electron oxidation of alkyl radical intermediate into carbocation species, and deprotonation.Graphical abstract
