METHYLNICKEL COMPOUNDS CONTAINING TRIMETHYLPHOSPHINE AND SALICYLALDIMINATO(N-O) LIGANDS

摘要

Methyl(salicylaldiminato[N:O])nickel complexes NiMe(2-O-C6H4-CH=NR)PMe(3) (R=Me, Ph, CHM(2), n-Bu, CH2CH(OMe)(2), CH2CF3) have been prepared from [NiMe(OMe)(PMe(3))](2) and the corresponding salicylaldimine. The diamagnetic methylnickel compounds contain the well known six-membered chelate ring and are unreactive towards excess trimethylphosphine. Steric demand of the N-substituent (R=CMe(3)) causes ring opening and ligand dismutation reactions at the nickel center. [References: 6]
