The first Ni-catalysed synthesis of di- and triamino substituted benzenes and diamino substitutedpyridines from the corresponding aryl chlorides and amines is described.

A simple route to synthesize mononuclear palladium(II) thiosemicarbazone complex has been described. Elemental analysis, spectral methods and single crystal X-ray diffraction analysis were used to confirm the composition of the complex. The new complex acts as an active homogeneous catalyst for the Buchwald-Hartwig amination reaction of a wide range of aryl and heteroaryl halides (bromides and chlorides), including activating, neutral and deactivating substrates, with various secondary amines under optimized conditions.

Selective monoamination of aryl and heteroaryl dichlorides has been carried out using a catalyst combination of Ni(0) associated to 2,2'-bipyridine. The synthesis of novel 3-chloroanilines and chloro aminopyridines in good to excellent yields is allowed using an excess of amine, 10 or 20 mol% catalyst and short reaction times.
