Abstract
The direct photolyses of the gamma-(3-methyl-1-phenyl-1,2-butadienyl)-sub a lpha,beta -unsaturated esters and nitriles gave the bicyclo[2.1.0]pentanes, cross-conjugated trienes, and several intramolecular products, while the t riplet-sensitization led to the former two compounds. It was found that the photochemoselectivity depended on the substituents on the vinyl group and would be controlled by the energy using the tripler sensitizers. (C) 2001 E lsevier Science Ltd.
