  New carbohydrate bisphosphites as chiral ligands

  摘要：

  The synthesis of the 2,3-bisphosphite derivatives of phenyl 4,6-O-benzylidene-beta-D-glucopyranoside leads to new chelating ligands. Their rhodium(I) and platinum(II) complexes have been tested as catalysts for the asymmetric hydroformylation of vinyl acetate, allyl acetate and p-methoxystyrene. Good regioselectivity (>90% branched product), but an enantioselectivity of only less than or equal to 36% ee were found under mild reaction conditions (25-40 degrees C, 40-70 bar syngas).

• Impact of Incorporating Substituents onto the P-<i>o</i>-Anisyl Groups of DiPAMP Ligand on the Rhodium(I)-Catalyzed Asymmetric Hydrogenation of Olefins

  The introduction of 1,2-bis[(o-anisyl)(phenyl)phosphino]ethane (DiPAMP) as a P-stereogenic ligand for rhodium(I)-catalyzed hydrogenation by Knowles et al. came after their evaluation of several diphosphines. However, no in-depth study was carried out on incorporating various substituents on its P-o-anisyl groups. In this work, we have prepared a large series of enantiopure and closely related DiPAMP

  Knowles等人引入1,2-双[（邻-茴香基）（苯基）膦基]乙烷（DiPAMP）作为铑（I）催化加氢的P-立体异构体。是他们对几种二膦进行评估后得出的。然而，没有深入研究关于其P-掺入各种取代基进行ö -anisyl基团。在这项工作中，我们制备了一系列对映体纯且密切相关的DiPAMP类似物，它们在o-茴香基环上具有各种取代基（MeO，TMS，t- Bu，Ph，稠合苯环）。新的配体在铑催化的几种模型底物的氢化反应中进行了评估：α-乙酰氨基丙烯酸甲酯，（Z）-α-乙酰氨基甲酸甲酯，（Z）-β-乙酰氨基丁酸巴豆酸酯，衣康酸二甲酯和抗风酸。它们显示出增强的活性和增加的对映选择性，特别是P-（2,3,4,5-四-MeO -C 6 H）取代的配体（4MeBigFUS）。有趣的是，在温和条件下（10 bar H 2，室温），使用Rh-（4MeBigFUS）催化剂在无水酸的氢化中获得了88％ee，而使用
• Structure‐Activity Relationships for Bis(phenolate‐ether) Zr/Hf Propene Polymerization Catalysts

  large, flat substituents in the o‐phenolate position; tuning of regioselectivity is much harder. Hf catalysts are slower than their Zr analogs and do not work well with MAO/BHT (BHT = 2,6‐di‐tert‐butyl‐4‐methylphenol); they are generally more selective (MW, stereo and regio). Density functional calculations agree fairly well with observed selectivities, supporting the involvement of a fac/fac coordinated

  测试了一系列20种双（酚酸酯-醚）配体，与Zr和Hf结合，用于丙烯聚合，重点研究了所得聚合物的分子量，立构规整​​性和区域规整性。配体变化涵盖了配体半体之间的脂肪族连接基的长度，以及酚酸氧邻位基团的空间体积。接头长度对MW显着的效果：二碳接头产生的低聚物（M Ñ <2.5 kDa的），而三和四碳接头产生高得多的MW（M Ñ通常50-500千道尔顿）。立体选择性可以使用o中的大而平坦的取代基来调节酚盐位置; 区域选择性的调节要困难得多。Hf催化剂比Zr类似物慢，并且不能与MAO / BHT一起使用（BHT = 2,6-二叔丁基-4-甲基苯酚）；它们通常更具选择性（MW，立体声和区域）。密度泛函计算与观察到的选择性非常吻合，支持了fac / fac协同活性物种的参与。这些O4催化剂比茂金属具有更大的柔韧性，因此，准确预测PP的微观结构成为一项重大挑战。
