摘要：

We studied the reactivity of an osmium vinyl complex containing a coordinated hydroxyl group OsCl2(PPh3)2[CH=C(PPh3)CHPh(OH)] (1) toward bidentate ligand 1,4-bis(diphenylphosphino)butane (DPPB),acid ligand (CO),base (Cs2CO3) and heat.Two osmium vinyl complexes OsCl2(dppb)[CH=C(PPh3)CHPh(OH)](2) and OsCl2(CO)2(PPh3)[CH=C(PPh 3)CHPh(OH)] (3),as well as two relatively rare phosphonium-containing osmafuran complexes Os(2-OCOO)(PPh3)2[CHC(PPh3)CPhO](4) and OsCl2 (PPh3)2[CHC(PPh3)CPhO](5),were obtained in high yields from these reactions.All products were characterized by NMR spectroscopy,elemental analysis,and their structures were further confirmed by single crystal X-ray diffraction.
