Efforts to link phosphinimide and cyclopentadienyl ligands via metathesis were undertaken. To this end, the allylic phosphinimine t-Bu2(CH2═CHCH2C(Me2)PNSiMe3 (1) and the Ti complexes t-Bu2(CH2═CHCH2C(Me2)PNTi(Cp)Cl2 (2), t-Bu2(CH2═CHCH2C(Me2)P

Complexes of the form (Nacnac)Ni(η 5 -L) (L = Cp (3), indenyl (4)) are readily prepared and have been protonated to generate the corresponding cationic species [(HNacNac)Ni(η 5 -L)][B(C6F5)4] (L = Cp (5), indenyl (6)). While the symmetric compound

The reductions of (Nacnac)Ti(III) complexes (Nacnac = (HC(CMeNC6H3(i-Pr)2)2) are examined. Treatment of (Nacnac)TiCl2 with K/Na alloy in the presence of CH2(PPh2)2 afforded the dark red product [K(C(Me)CHC(Me)NAr)Ti(NAr)(μ-H)]2 (2). This Ti(III)-imi

The compound (Nacnac)Ni(μ-Br)2Li(THF)2 (Nacnac = (HC(CMeNC6H3(i-Pr)2)2) was reduced by reaction with K/Na alloy in toluene. The resulting product [((Nacnac)Ni)2(μ-η3:η3-C6H5Me)] (1) was characterized and is best described as a Ni(II) species in w
