coordination complex di‐μ‐hydroxobis[(N,N,N′,N′‐tetramethylethylenediamine)copper(II)] chloride [Cu(κ2‐N,N‐TMEDA)(μ‐OH)]2Cl2} have been highly efficient in C–C and C–heteroatom bond formationprocesses. This new catalytic system has proved its performance in C–N couplings and in the synthesis of differently substituted propargylic amines through cross‐dehydrogenative couplings, multi‐component reactions such

nitrosation was never observed, but minor amounts of m- and p-nitro amines and/or nitrosamines were formed in some cases. Ring nitration is rather a reaction of the initial substrate than a process occurring on formed nitrosamines. The leaving propensities of the initial N-substituents to yield nitrosamines were in the order benzylmethyl alkyl.

A new reagent system, a combination of iodic acid and sodium nitrite has been investigated for oxidative coupling of N,N-disubstituted anilines. A facile para-selective coupling occurs to give benz...
