Synthesis and reactivity of nickel-hydride amino-bis-phosphinimine complexes

Abstract

Cationic hydride complexes [R–N(1,2-CH₂CH₂NPPh₃)₂NiH][PF₆] (R = H, Me) are prepared and shown to react with ethylene to produce NiEt complexes and with LiHBEt₃ in bromobenzene to produce NiPh complexes. These species are also thermolysed at 80 °C to orthometallate one of the phenyl groups of the NPPh₃ substituents.
