The reaction of N,N-diethylamino-tributyltin with aryl bromides in the presence of a catalytic amount of PdCl2(o-tolyl3P)2 gave N,N-diethylaminobenzene derivatives. The reaction is a new kind of amination different from ones through aryne or SRN1 mechanise

The mechanism of the C–N cross-coupling reaction, catalyzed by palladium complexes with N-heterocyclic carbene ligands (Pd/NHC), was evaluated in detail at the molecular and nanoscale levels. For the first time, the formation of a “cocktail”-type catalytic system was proven for the Buchwald–Hartwigreaction. The unique ability of the Pd/NHC system to generate several types of catalytic centers (Pd
