    施罗克型钼亚烷基络合物的空气稳定性:烯烃复分解的用户友好型预催化剂
    摘要:
    方便的问题:Schrock钼亚烷基是迄今为止已知最强大的烯烃复分解催化剂之一,但它们对空气和湿气的敏感性要求它们在手套箱中或通过Schlenk技术进行处理。使用相应的菲咯啉或联吡啶加合物可以避免这种不便,它们是稳定的,因此非常易于使用。在甲苯中用ZnCl 2处理时,活性物质可以毫不妥协的形式从这些预催化剂中释放出来(参见方案)。

    Highly active, recoverable and recyclable transition metal-based metathesis catalysts and their organometallic complexes including dendrimeric complexes are disclosed, including a Ru complex bearing a 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene and styrenyl ether ligand. The heterocyclic ligand significantly enhances the catalytic activity, and the styrenyl ether allows for the easy recovery of the Ru complex. Derivatized catalysts capable of being immobilized on substrate surfaces are also disclosed. The present catalysts can be used to catalyze ring-closing metathesis (RCM), ring-opening (ROM) and cross metatheses (CM) reactions, and promote the efficient formation of various trisubstituted olefins at ambient temperature in high yield.

    A composition and method for the catalytic conversion of a racemic mixture of dienes to a cyclic olefin by a ring-closing metathesis (RCM) reaction are disclosed. The composition, a transition metal complex with an M═C reaction site, contains a bidentate dialkoxide of at least 80% optical purity. Because the M═C reaction site is of a sufficient shape specificity, conferred in part by the dialkoxide of sufficient rigidity and a M═N—R1 site, reacting the composition with a mixture of two enantiomeric dienes results in an olefin metathesis product that has at least a 50% enantiomeric excess of one enantiomer in the mixture. A method is also provided for reacting a composition with a racemic diene mixture to generate a metathesis product that has an enantiomeric excess of at least 50%. Methods are also provided for catalytic enantioselective desymmetrization. One method involves an olefin metathesis reaction with a molecular substrate having a plane of symmetry to form a product free of a plane of symmetry. Another method provides a desymmetrization reaction to occur in the absence of solvent. A method for producing quaternary carbon centers through a desymmetrization reaction is also described.
    揭示了一种用于催化将二烯的外消旋混合物转化为环烯烃的组合物和方法,通过环闭合茂合反应(RCM)。该组合物是一个过渡金属配合物,具有一个M═C反应位点,含有至少80%光学纯度的双醚基。由于M═C反应位点具有足够的形状特异性,部分由足够刚度的双醚基和M═N—R1位点赋予,将该组合物与两个对映异构的二烯混合物反应会产生至少一个对映异构体的烯烃茂合物产物,其在混合物中具有至少50%的对映异构体过量。还提供了一种方法,用于将组合物与外消旋二烯混合物反应,生成具有至少50%对映异构体过量的茂合物产物。还提供了用于催化对映选择性非对称去对称化的方法。一种方法涉及与具有对称面的分子底物进行烯烃茂合反应,形成无对称面的产物。另一种方法提供了在无溶剂存在的情况下进行去对称化反应的方法。还描述了通过去对称化反应产生季碳中心的方法。
