UV-induced catalyst-free intramolecular formal heck reaction

الملخص EN

A 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 CAI bond, addition of the aryl radical to the alkene moiety, single electron oxidation of alkyl radical intermediate into carbocation species, and deprotonation
