摘要：
Photochemical cleavage of Ar-O bonds in phenyl esters substituted with electron-donating groups offers a convenient method for the arylation of alkenes and arenes. The reaction proceeds by an SN1 mechanism via a triplet phenyl cation to form allylbenzene or biphenyl derivatives under mild conditions (see scheme). © 2005 Wiley-VCH Verlag GmbH & Co.
