摘要
Reaction of bis{trimethylsilyliminodi(phenyl)-phosphorano}methane, H2C(Ph2P=NSiMe3)(2) (1) with 1 equiv of trimethylaluminum in toluene gave a four-coordinated alkyl aluminum complex of the formula [AlMe2{HC(Ph2P=NSiMe3)(2)-kappa(2)N,N'}] (2) via the elimination of methane. The crystal structure confirms the monomeric nature of the complex: and the bidentate coordination of the bisiminophosphoranomethanide ligand to aluminum. Reaction of 1 with 2 eguiv of trimethylaluminum yielded the novel bimetallic complex [(AlMe2)(2){mu(2)-C(Ph2P=NSiMe3)(2)-kappa(4)C,C',N,N'}] (3), in which the methylene backbone carbon has been doubly deprotonated.
