Abstract
Oxidative cleavage of a range of ylides 4 with R(1) and/or R(2) being aromatic groups, using KMnO4 in a two-phase system, affords unsymmetri cal benzils and 1-arylpropane-1,2-diones 5 in moderate to good yield, and the ylide formation and oxidation can be combined in a convenient one-pot method.
