A terphenyl phosphine ligand (2,6-bis(2,4,6-triisopropylphenyl)phenyl-dicyclohexylphosphine, TXPhos) and its supported palladium complex [(TXPhos)(allyl)PdCl] have been developed and the catalyst system is highly efficient in amination of arylhalides with 1° anilines, especially effective for densely functionalized substrates including both partners possessing ortho-ester, acetyl, nitrile and nitro

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.
Bulky diadamantyl aryl phoshine ligands were synthesized and utilized in Buchwald‐Hartwig couplingreactions of sterically demanding ortho‐substituted arylchlorides. The ligands also showed enhanced catalytic activity in the coupling of tosyl hydrazones and aryl halides.
