Two Metals Are Better Than One in the Gold Catalyzed Oxidative Heteroarylation of Alkenes [PDF]
, 2011 We present a detailed study of the mechanism for oxidative heteroarylation, based on DFT calculations and experimental observations. We propose binuclear Au(II)–Au(II) complexes to be key intermediates in the mechanism for gold catalyzed oxidative ...
