چکیده
Cationic hydride complexes [R-N(1,2-CH(2)CH(2)N=PPh(3))(2)NiH][PF(6)] (R = H, Me) are prepared and shown to react with ethylene to produce NiEt complexes and with LiHBEt(3) in bromobenzene to produce NiPh complexes. These species are also thermolysed at 80 °C to orthometallate one of the phenyl groups of the N=PPh(3) substituents.

Non-innocent reactivity of bis-phosphinimine pincer ligands in palladium complexes.
Although the Pd complex of the bis-phosphinimine pincer ligand 1,3-C(6)H(3)(CH(2)N=PPh(3))(2) is accessible, this ligand is also non-innocent in the formation of a phosphinimine-aminophosphine pincer complex; as well, both complexes undergo hydride abstraction generating unique formally cationic ligand complexes.

Nickel (II) and copper (II) complexes of highly unsymmetrical tetradentate Schiff base have been synthesized by the template reaction of half-units N-(1-hydroxy-2-acetonaphtone)-1-amino-2-phenyleneimine (HL) and N-(2-hydroxyacetophenone)-1-amino-2-phenyleneimine (HL1) with the glyoxalphenylhydrazone. The complexes have been characterized by elemental analyses, conductance, IR, 1H NMR and UV spe...
متن کاملThermally stable rare earth dialkyl complexes supported by a novel bis(phosphinimine)pyrrole ligand.
A novel bis(phosphinimine)pyrrole based ligand (HL) and its synthesis are reported. Rare earth dialkyl complexes of the ligand, LLn(CH(2)SiMe(3))(2) (Ln = Er, Lu, Sc), have been prepared and found to exhibit high thermal stability in solution. The protio-ligand and dialkyl lanthanide complexes (Ln = Er, Lu) have been characterised by single crystal X-ray diffraction studies.

متن کاملStable bis(trifluoromethyl)nickel(III) complexes.
Organometallic Ni(III) intermediates have been proposed in several Nickel-catalyzed cross-coupling reactions, yet no isolated bis(hydrocarbyl)Ni(III) complexes have been reported to date. Herein we report the synthesis and detailed characterization of stable organometallic Ni(III) complexes that contain two trifluoromethyl ligands and are supported by tetradentate N-donor ligands (R)N4 (R = Me ...
