Decoding the redox behaviour of copper in Ullmann-type coupling reactions

The copper-catalysed functionalization of aryl halides is one of the most preferred methods for the formation of carbon-carbon and carbon-heteroatom bonds.1 Yet, the redox behaviour of the copper species in the catalytic cycle remains elusive and a subject of considerable debate.2 We report experimental and theoretical mechanistic investigations into the reaction of a well-defined Cu(I) complex with an electron-poor aryl …
