✦ Synopsis
Hydridoplatinum-molybdenum or tungsten heterodinuclear complexes dppe HPt-MCp CO M s Mo 1 , W 2 ; 3 Ž . x dppe s 1,2-bis diphenylphosphino ethane have been prepared by selective b-hydrogen elimination of corresponding eth-Ž . Ž . Ž . w Ž . Ž .x ylplatinum-molybdenum or tungsten complexes dppe EtPt-MCp CO M s Mo 3 , W 4 . The b-hydrogen elimination 3 Ž . Ž . process is significantly facilitated by electron-withdrawing transition metal ligand at platinum such as Co CO 5 . 4
Acetylenes having electron withdrawing groups induce selective hydride transfer reaction in these heterodunucelar complex Ž . Ž . 1-2 to give hydridomolybdenum or tungsten and zero-valent acetylene platinum complexes.
