title: Nucleophilic and electrophilic double aroylation of chalcones with benzils promoted by the dimsyl anion as a route to all carbon tetrasubstituted olefins.
abstract: 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.
