Abstract

Abstract: The photoisomerization of alkyl-substituted bicyclo [3.1. O] hexan-2-ones has been studied. Using the n 6 A* excitation, two different isomerizations have been found: one route involves opening of the cyclopropane ring with hydrogen migration to give an unsaturated ketone, the other route a type I a cleavage independent of the cyclopropane ring. Opening of the cyclopropane ring as a primary photochemical reaction only occurred when the 3 ...
