Abstract

Treatment of the coordinatively unsaturated osmium trimethylstannyl complex, Os(SnMe₃)Cl(CO)(PPh₃)₂ 1, with either pyridine (py) or sodium acetate results in methyl migration from tin to osmium, giving the structurally characterised complexes, Os(Me)(SnClMe₂)(py)(CO)(PPh₃)₂ 2 or Os(Me)(SnMe₂OC[Me]O)(CO)(PPh₃)₂ 3, respectively: the methyl migration is reversible and treatment of Os(Me)(SnClMe₂)(py)(CO)(PPh₃)₂ with CO gives the trimethylstannyl complex, Os(SnMe₃)Cl(CO)₂(PPh₃)₂.
