An effective and robust iridium pincer complex achieves a selective α-alkylation of tertiary and secondary acetamides involving a borrowing hydrogen methodology. The method tolerates alcohols bearing various functional groups. This presents a convenient and environmentally benign protocol for α-alkylation of amides.
