series of N-heterocycliccarbene-palladium(II) chlorides-1-methylindazole and -1-methylpyrazole complexes was successfully synthesized and fully characterized by X-ray single crystal diffraction. In addition, initial investigations of their catalytic activity showed that they were efficientcatalysts in the C–N coupling of primary and secondary amines with aryl chlorides at low catalyst loadings.

chelating alkylphosphines for the amination of heteroaryl and aryl chlorides, bromides, and iodides. In the presence of this catalyst, aryl and heteroarylchlorides, bromides, and iodides react with many primary amines in high yields with part-per-million quantities of palladium precursor and ligand. Many reactions of primary amines with both heteroaryl and aryl chlorides, bromides, and iodides occur to

The N-arylation of various amines with arylchlorides proceeded in good-to-excellent yields in the presence of P[N(p-NMe2)C6H4CH2}CH2CH2]3N (1e, a new electron-rich proazaphosphatrane ligand) and small amounts of Pd2(dba)3 (dba = dibenzylideneacetone). This catalytic system was also very effective for the synthesis of carbazoles.

N-(1-Oxy-pyridin-2-ylmethyl)oxalamicacid was identified as efficientligand for CuI-catalyzed amination of aryl halides at roomtemperature. In our catalytic system, N-arylation of cyclic secondary amines, primary amines, amino acids, and ammonia proceeded with moderate to excellent yields and high functional group tolerance.
