Oil-soluble phosphonium-based ionic liquids (ILs) have recently been reported as potential ashless lubricant additives. This study is to expand the IL chemistry envelope and to achieve fundamental correlations between the ion structures and ILs' phys

The first thermally stable, neutral, electrophilic phosphinidene complexes of vanadium, [CpV(CO)3{η1-P(NR2)}] (R = iPr (3a), Cy (3b)), have been prepared by the reaction of [Na]2[CpV(CO)3] with Cl2PNR2. The molecules 3a and 3b have been characterize

The reaction of the titanacycle CpTi(NPt-Bu3)(C4H8) (1) with benzyl halides, 4-bromo-1-butene, and allyl chloride proceeds with loss of ethylene to give CpTiX(NPt-Bu3)(CH2Ph) (X = Cl, 3; Br, 4), CpTiBr(NPt-Bu3)(CH2CH2CHCH2) (5), and CpTiCl(NPt-Bu3)(C

Reaction of the methylene-bridged complex [RhOs(CO)3(μ-CH2)(dppm)2][CF3SO3] (dppm = μ-Ph2PCH2PPh2) with dimethyl acetylenedicarboxylate or hexafluorobutyne results in alkyne insertion into the Rh−CH2 bond, yielding [RhOs(CO)3(μ-η1:η1-RCC(R)CH2

The redox chemistry of phosphinimide-containing group IV metal complexes has been investigated. Reaction of the simple phosphinimide species CpTi(NPR3)Cl2 (R = Me 1, i-Pr 2) with Mg affords complexes formulated as [CpTiCl(μ-NPR3)]2 (R = Me 3, i-Pr 4

The syntheses of a series of bifunctional ligands, in which a cyclopentadienyl and a phosphine group are linked by either a CH2 or a C2H4 fragment (-C5H4(CH2)nPR2; n = 1, 2; R = Me, Ph), are reported, as is that of the related ligand, Li2[Me2C(C5H3CM
