Organic Iodide Aided Carbonylation of Terminal Acetylenes with Palladium Catalyst

Torii, S.; Okumoto, H.; Sadakane, M.; Xu, L. H. Chem. Lett. 1991, 1673.

Carbonylation of various terminal acetylenes in the presence of a catalytic amount of organic iodides or amine･HI salt and palladium complexes was found to produce 2-substituted acrylamides in good yields under mild conditions (5 atm, 120 ｡C, 6 h).
