The N-arylation of various amines with aryl chlorides 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. An efficient palladium-catalyzed N-arylation reaction of amines under mild conditions with a tuned bicyclic proazaphosphatrane has been developed.

As a part of a research program related to the synthetic study of pharmacologically and photoconductively interesting pyrrole derivatives, we have synthesized 1-arylpyrroles (3a-e), 9-arylcarbazoles (4a-e), aminophenylpyrroles (6a,b), dipyrrolylbenzenes (7a-c), 2,4,6-tri-pyrrol-1- yl-pyrimidine (8) and 2,4,6-tri-pyrrol-1-yl[1,3,5]triazine (9). We proposed a plausible mechanism for the formation of 9-arylcarbazole.
