The photochemical ring opening and ring cleavage reactions of 6b,8a-dihydrocyclobut[a]acenaphthylene (1) and two similar compounds are described. These reactions occur at room temperature only if the irradiating light intensity is greater than MW/cm2, easily obtained with excimer and dye lasers. Th

The synthesis of di(a-thieny1)hexamethyltrisilane (1) is described. In the photolysis of 1 with cyclohexene and methanol, an apparent radical reaction occurred. We suspect that the sulfur atom of the thienyl group strongly stabilizes an initially formed silyl radical. This idea was supported both by
