    Chemo-, regio- and stereoselective conversion of P-chirogenic phosphorus borane complexes into their PO or PS derivatives
    摘要:
    Chiral and achiral organophosphorus borane complexes are readily transformed into their corresponding phosphoryl or thiophosphoryl compounds in high yields using one-pot procedures with stereoselectivities reaching 100% in many cases. Both oxidation and sulfuration were performed under neutral or mild conditions and were applied to various organophosphorus borane complexes (phosphines, phosphinates, chlorophosphines, aminophosphines, etc.). In the case of the dissymmetric diphosphine or aminophosphine phosphinite ligands, the reaction of their diborane complexes proceeds regiospecifically to a single phosphorus group, affording the corresponding hybrid derivatives.

    5-Exo-trig radical reductive cyclization reactions of bromoacetals are catalyzed by iron in the presence of the reducing agent NaBH4. Both iron(II) and iron(III) were found to effectively mediate these reactions. As shown by cyclic voltammetry, iron(III) can be reduced to an iron(II) precatalyst before passing through an identical reaction mechanism in which monoelectronic activation of the substrate

    A new versatile method for the synthesis of supported mono and diphosphines on polypyrrole matrix is described, based on the protective borane complexation of the phosphorus atom. For the first time, the unknown alkylation of a diphosphine ethano bridge, was obtained with near yield close to 70%, leading to its derivative 8 bearing the polymerizable pyrrole group on a side chain. The different supported
    基于原子的保护性硼烷络合,描述了一种新的通用方法,用于在聚吡咯基质上合成负载的单膦和二膦。首次以接近70%的收率获得了未知的二膦乙烷桥的烷基化反应,从而导致其衍生物8在侧链上带有可聚合的吡咯基团。所支持的不同的单和二膦硼烷12 - 15已经被应用在催化的烯丙基化,交叉偶联反应和在催化的加氢成功。特别令人感兴趣的是,可以使用负载的膦硼烷而无需事先分解,从而原位形成Pd(OAc)2的催化活性物质。或RhCl 3。此外,可回收的聚合物可以在几次翻转之后以非常好的效率再次用于催化的氢化中。尽管如此,我们可能会指出,在催化下,必须添加Pd(dba)2才能恢复催化活性。这些结果表明,膦硼烷配合物是用于合成官能化的单膦和二膦以及它们直接用于产生催化剂的关键前体。
