RuCl2(p-cymene)/DPPE catalyzed addition of secondary amines and CO2 to terminal alkynes affording anti-Markovnikov adducts of vinyl carbamates in good yield with excellent regioselectivity is reported. The catalyst, consisting of labile p-cymene displays very high regioselectivity towards the anti-Markovnikov adducts and was applicable to a variety of aliphatic/aromatic alkynes and secondary amines.

Terminal alkynes with secondary amines (dimethylamine, diethylamine, piperidine, morpholine) and CO2 in the presence of mononuclear ruthenium catalysts, afford the vinylcarbamates R1CHCHOCONR2. The reaction studies suggest, as the active catalytic species, a ruthenium-vinylidene intermediate.
