Cobalt-catalyzed reductive arylcarboxylation of t-butyl acrylate is demonstrated with electrophilic aryl bromides and carbon dioxide, cheap cobalt chloride as precatalyst, and zinc dust as a reductant. The reaction has excellent regioselectivity and functional-group compatibility and is suitable for a range of aryl bromides.
