    通过使1-取代的-3-甲基-3-膦-1-氧化物与草酰氯反应,开发了一种新型的1-氯-3-甲基-3-磷酰氯的制备方法。使获得的环状氯盐与LiBH 4反应,得到相应的1-取代的-3-甲基-3-膦基硼烷。后一种方案涉及无硅烷的脱氧和硼烷络合物的形成。在一种情况下,通过在环氯phosph盐中双键的重排来合成2-膦硼烷和相应的P-氧化物。通过量子化学计算研究了这种双键迁移。

    Platinum(II) complexes incorporating racemic and optically active 1-alkyl-3-phospholene P-ligands: Synthesis, stereostructure, NMR properties and catalytic activity
    摘要:
    Three 1-alkyl-3-phospholene 1-oxides, such as the P-ethyl, P-isobutyl and P-isopentyl derivative were prepared in racemic and enantiopure forms. After deoxygenation, the cyclic phosphines were converted to the corresponding phosphine-boranes and phosphine-platinum complexes (PtCl2L2, where L 1-alkyl-3-phospholene). The new products were characterized by spectral methods, and the stereostructure of the complexes was also evaluated by high level quantum chemical calculations. The platinum complexes were tested in the hydroformylation of the styrene. The extent of the regioselectivity towards branched aldehyde exceeds that measured with earlier platinum complexes. However, the enantioselectivity remained below 29%. (C) 2013 Elsevier B. V. All rights reserved.

    New P-alkyl 2,3-oxaphosphabicyclo-[2.2.2]octene 3-oxides were synthesized by the Bayer–Villiger oxidation of the corresponding 7-phosphanorbornene 7-oxides and were used as precursors for reactive alkylmetaphosphonates useful in the phosphonylation of alcohols. This is the first case that the reactivity of the two regioisomers formed by O-insertion was differentiated and that the fragmentation-related
