Abstract

The interaction of o-tolylmagnesium bromide or AlPh3(OEt2) with osmium tetraoxide leads to the isolation of the homoleptic, tetrahedral osmium(IV) compounds OsR4(R = C6H4Me-o or C6H5). Thermally stable M (C6H11)4 compounds (M = Ru, Os, or Cr; C6H11= cyclohexyl) are obtained by the interaction of the Grignard reagent with Ru2(O2CMe)4Cl, Os2(O2CMe)4Cl2, and CrCl3(thf)3(thf = tetrahydrofuran) respectively. The structures of all five compounds have been determined by X-ray crystallography.

Abstract

The 2,6-dixylyl-4-phenylphosphabarrelene has been synthesised from the parent phosphinine and its properties as a ligand explored through the preparation and characterisation of the complexes W(CO)(5)(L), Re(CO)(4)(L)Cl, (eta(6)-cymene)RuCl(2)(L), [(eta(5)-Me(3)SiC(5)H(4))Fe(CO)(2)(L)]PF(6), Rh(1,5-COD)(L)Cl, Ir(1,5-COD)(L)Cl, and cis-Pt(L)(2)Cl(2), where L = 4-phenyl-2,10-bis-(2,4-dimethylphenyl)-4H-1,4-ethenophospholine ((x)PB), cymene = 4-isopropyltoluene, eta(5)-Me(3)SiC(5)H(4) = trimethylsilylcyclopentadienyl and 1,5-COD = 1,5-cyclooctadiene. The new complexes were characterised by spectroscopic and analytical techniques and, for [(eta(5)-Me(3)SiC(5)H(4))Fe(CO)(2)(L)]PF(6) and Ru(eta(6)-cymene)(L)Cl(2), by single-crystal X-ray structure determination. The coordination properties of the phosphabarrelene have been established and compared with analogous complexes of triarylphosphines and triarylphosphites. Most spectroscopic and structural indicators suggest that the phosphabarrelene has coordination behaviour similar to that of simple triarylphosphines such as PPh(3).

Abstract

Interaction of [Ru2(O2CMe)4] Cl with Grignards acting as reducing agents in ethers has led to isolation of the yellow-brown complex Ru2(µ-O2CMe)4·(C4H8O)2 whose structure has been determined by X-ray crystallographic analysis; the complex is the first carboxylate with a Ru24+ core.

Abstract

The compounds OsR4, R = cyclohexyl, o-methylphenyl, have been isolated by the interaction of the appropriate Grignard reagents with Os2(O2CMe)4Cl2 and Os4O4 respectively; both complexes have been characterized by X-ray crystallography.
