WebAbstract Proton-coupled electron transfers (PCET) are unconventional redox processes in which an electron and proton are exchanged together in a concerted elementary step. While these mechanisms are recognized to play a central role in biological redox catalysis, their applications in synthetic organic chemistry have yet to be widely established. WebJun 24, 2013 · Concerted proton-coupled electron transfer is a key mechanism of substrate activation in biological redox catalysis. However, its applications in organic synthesis … WebBy using photoredox proton-coupled electron transfer (PCET)/Ni dual-catalysis, a highly regio- and diastereoselective amidoacylation of unactivated olefins has been developed. Various acyl electrophiles are compatible, including alkyl- and aryl acyl chlorides and anhydrides, as well as in situ activated carboxylic acids. purple rain minnesota tour
