Transition metal-catalyzed cross dehydrogenative coupling is an important tool for functionalization of the α Csp3-H bond of amines. Among this reaction category, copper-catalyzed selective C-C bond formation under atmospheric O2 is

A novel consecutive one-pot synthesis of pyrazolines and pyrazoles starting from simple aryl halides, styrenes, carbon monoxide, and hydrazines has been established. Palladium-catalyzed carbonylative vinylation of aryl halides gave the corresponding chalcones, which are trapped in situ by addition of hydrazines.
