Abstract

The cleavage of the aryl C−X bond under UV-irradiation and its subsequent addition into an intramolecular alkyne moiety have been studied carefully. By simply regulating the addition of electron donor, highly chemoselective intramolecular hydroarylation and haloarylation reactions were achieved, providing efficient methods for the synthesis of 9-benzylidene-9H-fluorene and 9-(halo(phenyl)methylene)-9H-fluorene derivatives.
