Copper-catalyzed functionalization of aliphatictertiaryamines with the assistance of C2Cl6 is described. This method details the alkynylation of aliphatictertiaryamines and the synthesis of methylene-bridgedbis-1,3-dicarbonylderivatives. The mechanism of the selective oxidation of aliphatictertiaryamines was also discussed. A broad spectrum of aliphatictertiaryamines was examined in this

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.
