photolysis of 2-alkenylcarboxamido-2-cycloalken-1-ones led regio- and stereospecifically to a faster [2+2] intramolecular reaction and therefore to the corresponding cyclobutanes. However, photorearrangements involving three different intramolecular H-abstraction processes, compete with the observed cycloaddition. To explain the results, we propose that different deactivation pathways are available
