Competition between inter- and intramolecular photocycloaddition reactions of 9-substituted anthracenes

Cao, Derong,Gao, Chunmei,Dobis, Silvia,Meier, Herbert

, p. 1995 - 2001 (2007)

A number of 9-[(arylmethoxy)methyl]anthracenes were prepared and their photoreactivity was studied. The intramolecular [4π+4π]cycloaddition competes with the intermolecular head-to-tail [4π+4π] cyclodimerization. The aryl substituents control the selectiv
