Abstract
- The investigation into the active copper(i) catalysts from copper(ii) precursors has become a fundamental and important task in copper catalysis. In this work, we demonstrate that the <superscript>t</superscript>BuO<superscript>−</superscript> anion serves not only as a base but also as a mediator to promote the reduction of Cu(ii) to Cu(i) in copper catalysis. XAFS and EPR spectroscopy evidence the [Cu(O<superscript>t</superscript>Bu)<subscript>3</subscript>]<superscript>−</superscript> ate complex as the key intermediate which undergoes homolytic-cleavage of the O–Cu(ii) bond generating [Cu(O<superscript>t</superscript>Bu)<subscript>2</subscript>]<superscript>−</superscript> ate complex.
