  Coordination behavior of phosphino-phosphaferrocenes: monodentate versus bidentate coordination to divalent palladium

  摘要：

  Two novel phosphino-phosphaferrocenes [eta(5)-C5H4(CH2)(n)PPh2]Fe(eta(5)-PC4H2-2,5-cy(2)) (PP1: n = 1; PP2: n = 2) have been designed and prepared in order to clarify weak chelate effect in the previously reported (eta(5)-C5H4CH2PPh2)Fe[eta(5)-PC4H2-2,5-((-)-menthyl)(2)] (1). P-31 NMR studies of reactions of PP1 with PdCl2(cod) (6) revealed that PP1 showed stronger tendency to coordinate to the Pd-II center in bidentate fashion compared to 1. On the other hand, chelate effect in PP2 was negligibly weak and a reaction of PP2 with 6 in a PP2/6 = 2/1 molar ratio gave a complex PdCl2(PP2)(2) (10) cleanly in which PP2 coordinated to the palladium center at the PPh2 moiety as a monodentate ligand. X-ray crystal structure studies of chelate complexes PdCl(2()PP1) (7) and PdCl2(PP2) (9) showed that 9 had deviations from an idealized geometry in the square planar complex which could be attributed to a larger chelate ring of PP2, while PP1 in 7 constructed nearly ideal geometry for the square planar complex.From comparison of the coordination behavior between 1, PP1, and PP2, it is concluded that steric bulk of (-)-menthyl groups in I is the main factor of the weak chelate coordination of 1.

  新型手性膦-二茂铁：其配位行为及其在钯催化的不对称烯丙基烷基化反应中的应用

  摘要：

  描述了一种新型手性膦基-磷二茂铁配体的合成。所述配体具有两个电子上独特的供体部分，并且取决于具有配位的过渡金属中心的化学计量，其表现为单齿的（具有游离的磷二茂铁）或二齿的配体。在钯催化的1,3-二苯基-2-丙烯基乙酸乙烯酯的不对称烯丙基烷基化反应中，观察到反应的对映选择性与Pd /膦基-膦二茂铁摩尔比之间存在明显的相关性。在手性配体的量不足（相对于Pd）的情况下，可获得最高的对映选择性（99％ee）。
