摘要

Metathetical and small molecule elimination reactions between appropriate transition metal carbonyl diphenylphosphorus complexes and organoaluminum compounds have been investigated as synthetic routes to transition metal derivatives of amphoteric ligands. The synthesis, characterization and properties of the starting compounds for the metathetical reactions, M(CO)5PPH2K.n(dioxane) M = Cr, W, n=2; Mo, n=1 from M(CO)5PPH2H and KH is described. All data confirm that the dioxane molecules in these complexes retain their identity as cyclic ethers. Subsequent reactions of Cr(CO)5PPH2K.2(dioxane) with AIR2Br, (R=Br,Me,Et,CH2SiMe3) in THF lead to the formation of high yields of fully characterized compounds with the empirical formula Cr(CO)5(PPh2(CH2)4OA1R2). The (CH2)4O unit arises from the cleavage of a THF molecule. No THF aluminum adducts are observed. The compound Cr(CO)5(PPH2(CH2)OA1(CH2SiMe3)2) which incorporates a new amphoteric ligand has also been characterized by an x-ray structural study.
