Abstract
Trimethyl-and triethyl-silane react with dodecacarbonyltriosmium at elevated temperatures or under u.v. irradiation in hexane to form the complexes R3SiOs(CO)4H, (R3Si)2Os(CO)4, and [R3SiOs(CO)4]2(R = Me or Et). These compounds are inter-related both thermally and upon further reaction with R3SiH. From the reaction between Me3SnH and Os3(CO)12 only Me3SnOs(CO)4H and (Me3Sn)2Os(CO)4 are isolated. Treatment of [Me3SiOs(CO)4]2 with sodium amalgam affords [Me3SiOs(CO)4]–, from which the species Me3SiOs(CO)4X (X = H, Me, SnMe3, or Ru(CO)4SiMe3) have been obtained. The n.m.r., i.r., and mass spectra of the new compounds are reported. A mechanism is proposed to account for the various products of the reactions between Group IVB hydrides R3MH and the dodecacarbonyls of the iron triad.Keywords
