  摘要：

  P-立体叔膦的实际合成在不对称催化、材料和药物化学中具有广泛的应用，是一项重大挑战。设计了一种由镍配合物催化的廉价和普遍存在的炔烃的区域和对映选择性氢膦化反应，其中原位制备了有毒和空气敏感的二级膦来自工作台稳定的二级氧化膦。这种方法已被证明具有前所未有的底物范围和官能团兼容性，可提供电子和结构多样化的 P(III) 化合物。这些产物可以很容易地转化为双齿配体和有机催化剂的各种前体，以及各种包含P和金属立体中心的过渡金属配合物。

  Reduction of phosphine oxides into the corresponding phosphines using PhSiH3 as a reducing agent and Ph3C+[B(C6F5)4]− as an initiator is described. The process is highly efficient, reducing a broad range of secondary and tertiary alkyl and arylphosphines, bearing various functional groups in generally good yields. The reaction is believed to proceed through the generation of a silyl cation, which reaction

  Phosphane-stabilized phosphenium cations react with silanes to effect either reduction to primary or secondary phosphanes, or formation of P–P bonded species depending upon counteranion. This operates for in situ generated phosphenium cations, allowing catalytic reduction of P(III)–Cl bonds in the absence of strong reducing agents. Anion and substituent dependence studies have allowed insight into

  Based on data for the acidity relationship of phosphines and phosphinous acids and water in dimethyl sulfoxide and water, a simple method is reported for the generation of phosphide and phosphinite anions by the action of concentrated aqueous alkali on primary and secondary phosphines as well as phosphinous acids in dimethyl sulfoxide or other dipolar aprotic solvents. Alkylation of the anion yields secondary and tertiary phosphines, polyphosphines, functionally substituted phosphines as well as similarly substituted phosphine oxides. Phosphinous acids have been alkylated in various solvents in two-phase systems containing concentrated aqueous alkali and tetrabutylammonium iodide as phase transfer catalyst.

  基于二甲基亚砜和水中的膦和亚膦酸与水的酸度关系数据，报道了一种简单的方法，通过浓碱水溶液作用于二甲基亚砜或其他偶极非质子溶剂中的伯膦、仲膦及亚膦酸，生成膦化物和亚膦酸根阴离子。通过烷基化反应，这些阴离子可转化为仲膦、叔膦、多膦、功能化取代膦及其类似取代的膦氧化物。在含有浓碱和四丁基碘化铵作为相转移催化剂的两相体系中，亚膦酸已在多种溶剂中进行烷基化。

  The reductive cleavage of phenylalkylphosphines Ph2PR, PhPR2 (R = Bu, iPr) with Na/NH3 is unselective: both phenyl and alkyl groups can be cleaved and Birch reduction may occur. Reaction of Ph2tBuP gives a high yield of diphenylphosphide. Polar groups (CO2Na, SO3,Na) at the ω position of primary alkyl groups may lead to an increase in selectivity; Birch reduction is suppressed and a functionalised

  苯烷基膦Ph 2 PR，PhPR 2（R = Bu，iPr）与Na / NH 3的还原裂解是非选择性的：苯基和烷基都可以裂解，并且可能发生桦木还原。Ph 2 tBuP的反应产生了高产率的二苯基磷化物。伯烷基的ω位置的极性基团（CO 2 Na，SO 3，Na）可能导致选择性增加；桦木还原得到抑制，并获得官能化的仲磷化物。

  Process for the preparation of tetrahydropterin and tetrahydropterin derivatives by hydrogenating pterin and pterin derivatives with hydrogen in the presence of a hydrogenating catalyst, in which the hydrogenation is carried out in a polar reaction medium and metal complexes that are soluble in the reaction medium are employed as the hydrogenation catalysts. The process is suited to the hydrogenation, particularly asymmetric hydrogenation, of folic acid, folio acid salts, folio acid esters, folio acid ester salts or dihydroforms thereof, with the proviso that in the event of using folic acid, carboxylic acid salts thereof or dihydroforms thereof the reaction medium is aqueous, and in the event of using folic acid esters, folic acid ester salts or dihydroforms thereof the reaction medium is an alcohol. The process opens up straightforward access to achiral and chiral pterin derivatives.

  通过在存在氢化催化剂的情况下，用氢气氢化葉酸和葉酸衍生物制备四氢生物葉酸和四氢生物葉酸衍生物的过程，其中氢化是在极性反应介质中进行的，并且可溶于反应介质的金属配合物被用作氢化催化剂。该过程适用于葉酸、葉酸盐、葉酸酯、葉酸酯盐或其二氢形式的氢化，特别是不对称氢化，但若使用葉酸、其羧酸盐或二氢形式，则反应介质为水，若使用葉酸酯、葉酸酯盐或其二氢形式，则反应介质为醇。该过程为得到无手性和手性葉酸衍生物提供了直接途径。
