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

The preparation of some novel 4H-pyrazolium salts is described.Unlike the structurally related 2H-imidazolium salts (1), the metho-salts (2) of 4H-pyrazoles show no exchange with deuterium at the N-methyl protons.Exchange occurs readily at a 5-methyl grou
