Abstract:Thermal decomposition of structurally related amido, alkoxo, and alkyl complexes of type [Ni(Me)(EC(H)RR′)(dippe)] (EC(H)RR′ = cyclo-NC4H8 (pyrrolidino), N(CH2Ph)2, OCH2Ph, OCH(Me)Ph, and CH2CH2Ph) takes place through formally analogous processes involving β-hydrogen elimination and reductive elimination of methane, cleanly affording corresponding Ni(0) imine, aldehyde, ketone, and olefin complexes, [Ni(η2-E═CRR′)(dippe)]. Kinetic studies on these decomposition reactions show that, in spite of their similarity, they involve substantial mechanistic differences.
