The complexes[M(CO)₃(CH₃CN)₃] (M=Mo, W) react with an equimolar quantity of PhSnCl₃ in dichloromethane at room tempreture to afford new heterobinuclear complexes[PhCl₂SnM(Cl)(CO)₃(CH3CN)₂] [M=Mo (1); W (2)].The complexes react with two equivalents of PR₂R'(R=Ph, R'=Ph, Me; R=Cy, R'=H) to yield stablecomplexes[PhCl₂SnM(Cl)(CO)₃(PR₂R')₂].Reaction of[PhCl₂SnM (Cl) (CO)₃(CH₃CN)₂]with one equivalent of PPh₂(CH₂)nPPh₂(n=I,2) or bulky phosphine ligands PBu₂^tCl in dichloromethane at room tempreture to give[PhCl₂SnMo(Cl)(CO)₃{PPh₂(CH₂)n-PPh₂}].CH₂Cl₂,[PhCl₂SnMo(Cl)(CO)₃PBu₂^tCl].CH₂Cl₂, respectively.The complexes 1 and 2 react with phosphite donor ligands P(OMe)₃ to give[PhCl₂SnM(Cl)(CO)₂-{P(OMe)₃}₃].All complexes have been characterized by elemental analysis, IR and ¹HNMR spectroscopies.Here we report the preliminary results of this work.
