摘要
The synthesis of alkoxy- and aryloxy- functionalized bisphosphanyl hydrazides, (RO)(2)PN(Me)N(Me)P(OR)(2), is described. Interaction of these ligands with transition metals, particularly rhodium(I), has been investigated. The steric effects around P-III centers have pronounced effects on the pathway of reactions of Rh(I) precursors. For example, the reactions of these ligands with [RhCl(CO)(2)](2) leads to the formation of carbonyl free, chlorobridged dinuclear complexes when the groups are relatively smaller (e.g., CH2CF3, Ph), whereas mononuclear carbonyl-containing complexes are formed with bulky substituents (e.g., C(6)H(3)Me(2)-2,6, C6H3(OMe)(2)-2,6).
