摘要：

Hydridoplatinum-molybdenum (or tungsten) heterodinuclear complexes (dppe)HPt-MCp(CO)(3) [M = Mo (1), W (2); dppe = 1,2-bis(diphenylphosphino)ethane] have been prepared by selective beta-hydrogen elimination of corresponding ethylplatinum-molybdenum (or tungsten) complexes (dppe)EtPt-MCp(CO)(3) [M = Mo (3), W (4)]. The beta-hydrogen elimination process is significantly facilitated by electron-withdrawing transition metal ligand at platinum such as Co(CO) (5). Acetylenes having electron withdrawing groups induce selective hydride transfer reaction in these heterodunucelar complex 1-2 to give hydridomolybdenum (or tungsten) acid zero-valent (acetylene)platinum complexes.
