Metal-amidato complexes: Synthesis, characterization, and reactivity of a diamidato-bis(phosphine) nickel(II) complex

摘要

Reaction of 1,2-bis-N-[2-(diphenyl-phosphanyl)benzoyl]diaminobenzene (H2N2P2: H(2)1) with Ni(ClO4)(2) produced the corresponding tetradentate diamidato-bis(phosphine) nickel(II) complex Ni(N2P2) (2). Reactivity studies of 2 with reductants yielded the orthometallated product [M+][Ni(N2PC)] ([M+][3]), where M = Cp-2*Co-III or NBu4 and N2PC = N-((2-diphenylphosphino)-benzoyl)-N'-((1-phen-2-idyl)oxomethyl)-1,2-diaminobenzene, via reductive cleavage of one of the PPh2 groups of H(2)1. The synthesis and characterization of the complexes are described. (C) 2014 Elsevier B.V. All rights reserved.
