Mediated by copper/diethyl azodicarboxylate, regioselective alkynylation of unactivated aliphatic tertiary methylamine with terminal alkyne was successfully established. It is not necessary for the tertiary methylamines to be aryl substituted to modulate the properties of amines. The alkynylation reaction described here has the advantage of simple operation, mild reaction conditions, good to excellent yields, and no need to exclude air and moisture.

In the presence of ZnBr2 and a manganese oxide-based octahedral molecular sieve (OMS-2), cross-dehydrogenativecoupling of a wide range of terminalalkynes and tertiary amines to propargylamines efficiently proceeded using molecular oxygen as the terminal oxidant.
