The coordination chemistry of iminooxosulphuranes VI. Factors affecting coordination geometry in complexes of tosyliminooxosulphurane

, p. 195 - 206 (1990)
The complexes (M = Ru, Rh, Os, Ir) have been prepared from the 16-electron complex or the corresponding tris(phosphine) compounds .The sulphinylamine cumulene adopts one of three possible bonding geometries (pyramidal, or coplanar through sulphur, or ?-coordination through sulphur and nitrogen).The preference for a particular mode in a given complex is discussed in terms of metal electron density, d-orbital occupancy, oxidation state and frontier orbital symmetry.Treatment of the complex (prepared from tosyliminooxosulphurane and ) with carbon monoxide results in a rearrangement of the ?-bond cumulene in the precursor to a pyramidally bound ligand in the CO adduct .
Novel Synthetic Routes to Disulphur and Disulphur Monoxide Ligands: Nucleophilic Attack at Co-ordinated Imino-oxo-λ4-sulphanes

The reactions of and with oxo-4-tosylimino-λ4-sulphane (4-MeC6H4SO2NSO) lead quantitatively to the adducts Cl(PPh3)2(4-MeC6H4SO2NSO)> = Os(NO) or Ir(CO)> which in turn are hydrolysed to the corresponding sulphur dioxide complexes Cl(PPh3)2(SO2)>.The iridium compound reacts cleanly with hydrogen sulphide to provide the disulphur monoxide complex whilst with hydrosulphide leads to the disulphur complex which may be oxidised to the corresponding S2O complex with 3-chloroperbenzoic acid.Alternatively, is accessible via the reaction of with cyclo-octasulphur.
