Reactions of sterically demanding phosphinimines R3PNH [R=i-Pr (1), t-Bu (2)] were examined. Reactions with B(C6F5)3 formed the adducts (R3PNH)B(C6F5)3 [R=i-Pr (3), t-Bu (4)] in high yield. On the other hand, 2 reacts with HB(OBu)2, evolving H2 to gi

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 preparation and structures of [Li(µ-NPt-Bu3)]4 1, [Li(µ-Cl)(HNPt-Bu3)]4 2, and [Li(µ-Cl)(HNPPh3)]4 3 are described. The structure of 1 stands in contrast to that of the only other known Li-phosphinimide derivative, [Li(µ-NPPh3)]6. The impact

A strategy for polymerization catalyst design has been developed based on the steric and electronic analogy of bulky phosphinimides to cyclopentadienyl ligands. To this end, the family of complexes of the form (Cp†)TiCl2(NPR3) has been prepared and

The preparation of a silyl−phosphinimide of the form (R3PN)SiMe3 (R = Me (1), i-Pr (2), Ph (3), t-Bu (4)) was achieved by the conventional literature methodology of oxidation of phosphine by N3SiMe3. The analogous species (t-Bu3PN)MMe3 (M = Ge (5),

Treatment of (butadiene)zirconocene with two molar equivalents of benzylmercaptane results in the formation of Cp2Zr(SCH2Ph)2 (11). Subsequent reaction of 11 with [Cp2ZrCH3 +][CH3B(C6F5)3 -](12) leads to rapid elimination of methane to yield the dinu

This paper focuses on the synthesis and reactivity of Cp*Ta(V)−phosphinimide complexes. Reaction of stoichiometric mixtures of Cp*TaCl4 and phosphinimine R3PNSiMe3 affords the complexes Cp*Ta(NPR3)Cl3, R = t-Bu 1, i-Pr 2. These species are readily

The reactions of Cp2MH3 (M = Nb, Ta) or Cp‘2NbH3 (Cp‘ = Me3SiC5H4) with excess primary phosphines yield the complexes Cp2NbH[(PPh)2] (1), Cp‘2NbH[(PPh)2] (2), and Cp2TaH[(PR)2] (R = Ph, 3; R = Cy, 4). Crystallographic studies of each of these c
