摘要

This work describes the hydroaminocarbonylation of alkynes with aliphatic amines without the addition of any acid additive. Excellent conversion and regioselectivity toward the formation of branched amides were obtained over a dppp-based Pd-catalytic system. The catalytic mechanism was studied and disclosed that the carbamoylpalladium complex intermediate instead of the widely accepted palladium-hydride (Pd-H) species was the active catalytic species for this reaction.
