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.
