Dimsyl anion promoted the polarity reversal of benzils in a Stetter-like reaction with chalcones to give 2-benzoyl-1,4-diones (double aroylation products), which, in turn, were converted into the corresponding tetrasubstituted olefins via aerobic oxidative dehydrogenation catalyzed by Cu(OAc)2.
Effects of strong π-electron accepting substituents on structure preference for thiocarbonyl ylide or thiirane

Equilibrium between thiocarbonyl ylide and thiirane depends upon the π-electron accepting nature of the substituents. Four carbonyl and ester groups move the equilibrium far to the thiocarbonyl ylide side.
