摘要：

The unsymmetrical PCPt pincer ligands {C6H4-l-CH2PPh2-3-CH2PBu2t} and {C6H4-l-CH2PPh2-3-CH2PPr2i} and the corresponding palladium complexes: PdCl{C6H3-2-CH2PPh2-6-CH2PBu2t} and PdCl{CH3-2-CH2PPh2-6-CHPPr2i} have been synthesized in good yields. The molecular structure of PdCl{C6H3-2-CH2PPh2-6-CH2Bu2t} was determined through a single crystal X-ray diffraction study. The palladium center was found to be located into a slightly distorted square planar environment in which the {C6H4-1-CH2Ph2-3-CH2Bu2t} ligand is coordinated as a tridentate, PCP pincer type chelate. The complex, PdCl{C6H3-2CH(2)PPh(2)-6-CH2PPr2i} catalyzes the Heck coupling of iodobenzene with styrene. (C) 2004 Elsevier B.V. All rights reserved.
