Gold-catalyzed synthesis of benzil derivatives and α-keto imides via oxidation of alkynes.


PMID 21332143

Abstract

An efficient process based on the gold-catalyzed redox reaction has been developed to oxidize 1,2-diarylacetylene or ynamide to 1,2-diaryldiketone or α-keto imide respectively. This process can tolerate a variety of functional groups and affords 1,2-dicarbonyl compounds in excellent yields under mild reaction conditions.
