The photosensitized (electron transfer)[4e + 2e] intramolecular cycloaddition of 1,1,8,8-tetraphenyl-1,7-octadiene; X-ray crystal structure of 4a,9a-trans-4a, 10-trans-1,2,3,4,4a,9,9a,10-octahydro-9,9,10-triphenylanthracene

Abstract

Irradiation of 1,1,8,8-tetraphenyl-1,7-octadiene in the presence of the electron transfer photosensitizer 1,4-dicyanobenzene results in the formation of a [4e + 2e] cycloadduct, the structure of which is determined by X-ray crystallographic analysis to be 4a,9a-trans-4a,10-trans-1,2,3,4,4a,9,9a,10-octahydro-9,9,10-triphenylanthracene.
