Abstract

A series of new binuclear Pd(II) complexes based on chelating diimines and bridging diphosphine or diimine ligands have been synthesized and characterized successfully. The formula of the new complexes are [Pd ₂(mbyp) ₂(DPA) ₂](PF ₆) ₄ (1), [Pd ₂(mbyp) ₂(DPE) ₂] (PF ₆) ₄ (2), [Pd ₂(mbyp) ₂(4,4-byp) ₂] (PF ₆) ₄ (3), [Pd ₂(mbyp) ₂(t-pye) ₂] (PF ₆) ₄ (4) [mbyp= 4,4-dimethyl-2,2- bipyridine, DPA= 1,2-bis(diphenylphosphino)acetylene, DPE= 1,2- bis(diphenylphosphino)ethylene, 4,4-byp= 4,4-bipyridine, and t-ype= trans 1,2-bis(4-pyridyl)ethylene)]. The catalytic activities of the new complexes have been investigated in the coupling of arylboronic acid derivatives to various olefins. Results obtained showed interesting catalytic activities and chemoselectivities for the new complexes in the coupling reactions to produce the conjugate addition and heck coupling products under free base or oxidant conditions.
