Abstract: The cyclometallated {M= Pd(II) or Pt(II)} complexes containing the N,N-dimethyl-1-(1-phenyl)ethylamine and its naphthylamine analogue were employed as reagents and reaction promoters for the insertion and C-C coupling reactions. Several hetero- and homo-bimetallic centres products were obtained from the insertion reactions involving the alkynylphosphine ligands. Furthermore, the aromatic C-H bond activation and C-C coupling reaction has resulted in the formation of the 6-membered metallacycle coupling products. The organoplatinum complex containing the N,N-dimethyl-1-(1-naphthyl)ethylamine was also utilized for the asymmetric Diels-Alder reactions between the 3,4-dimethyl-1-phenylphosphole (DMPP) and various arsino- as well as phosphino-substituted furan ligands. Similarly, this chiral metal template was used in the asymmetric Diels-Alder reactions involving the diphenylvinylarsine and phosphine with the arsino- and phosphino-substituted furan cyclic dienes thereby yielding several optically active arsinophosphine ligands.
