Abstract

Summary: An examination of substituent effects upon the photochemistry of a number of 1, 5- hexadien-3-ones reveals a close parallel with those observed in the cyclization of 5-hexenyl radicals and permits for the first time a rationalization for variations in the regiospecificity of the intramolecular [2+ 21 cycloaddition reactions of these dienones.
