In this work, photochemical reactions of 2-(2’-alkenyloxy)cycloalk-2-en-1-ones were investigated and three main reaction pathways were found depending on the enone ring size and the substitution pattern of the double bonds. Products were obtained from crossed [2+2] photocycloaddition, a cyclization/hydrogen abstraction cascade, or [2+2] photodimerization. Attempts to perform the reaction enantioselectively were unsuccessful. Additionally, UV/vis studies on three thiocarbonyl compounds were performed.
