Abstract
AbstractWe describe herein that the cross‐coupling of bromodifluoroacetamides with (iodoethynyl)arenes proceeds without recourse to any photocatalyst when exposed to visible light at room temperature to afford alkynyldifluoroacetamides in 62–83% yields (27 examples). Several control experiments suggest that the reaction involves the homolysis of bromodifluoroacetamides and the coupling of the resultant difluoromethyl radical species with the 1‐iodoalkynes via a radical chain process. Divergent transformations of the coupling products led to various organofluorine compounds, demonstrating the synthetic utility of the developed photo‐coupling method.magnified image
