  Palladium(II), Platinum(II), and Iridium(I) Complexes of 2-Phosphino-1-dimethylaminoferrocenes: A Survey of Structure and Catalysis

  摘要：

  A series of PdCl2, PtCl2 and Ir(COD)BArF. complexes bearing a rare class of racemic bidentate 2-phosphino-1-dimethylaminoferrocene ligands were prepared and characterized by NMR spectroscopy and X-ray crystallography. The new complexes displayed a structural trend relating a decrease in heteroatom-metal bond length with an increase in ligand bite angle on going from Ir to Pd and Pt. The pdCl(2) and PtCl2 complexes were almost isostructural and featured MCl2 moieties in the plane of the substituted Cp ring of the ligand. In contrast, the Ir(COD)(4)complex was distinguished by a bend of the Ir(COD) moiety toward the unsubstituted (Cp') ring. The latter gave rise to a steric interaction that placed the Cp rings in almost eclipsed conformations. Ligand 8a (2-diphenylphosphino-1-dimethylaminoferrocene) was able to promote Pd-catalyzed Suzuki-Miyaura and Buchwald-Hartwig coupling of aryl chlorides in addition to Ir-catalyzed hydrogeriation of electron-deficient and unactivated alkenes. A preliminary intramolecular hydroamination of a terminal alkene using 8a in conjunction with lr(l) afforded the cyclized product in 64% yield.

  平面手性2-膦-1-氨基二茂铁-铱（I）配合物对烯烃的不对称氢化

  摘要：

  报道了第一个高度对映体富集和对映体纯的平面手性2-膦基-1-氨基二茂铁配体及其Ir（COD）BAr F配合物。如膦部分的31 P和1 H NMR光谱以及胺的α至氮取代基的趋势所示，这些配体显示出对铱的二齿配位行为。所有这些新的配合物均表现出良好的反应活性，可作为催化剂促进多种手性烯烃的不对称氢化，对映选择性高达92％。含P -Ar基团[PPh 2和P（o- tol）2的二甲基氨基二茂铁衍生物的铱配合物给出了最高水平的不对称诱导。
