    苯酚和邻苯二酚的催化好氧交叉脱氢偶联
    摘要:
    我们描述了创建芳基醚的苯酚和儿茶酚的选择性催化有氧交叉脱氢偶联(CDC)反应。为避免选择性挑战,我们采用铜(Cu)配位将底物氧化还原限制在金属的内部配位球中。这可以最大程度地减少非选择性自由基过程,从而通过C–O而不是C–C键的形成为交叉均质偶联提供高水平的选择性。该方法在合成有用的底物和规模上仍然有效,并且能够收敛合成四氢异喹啉生物碱(S,S)-thalicarpine具有在合成后期形成二芳基醚的特征。相关分子很难通过传统的Ullman型偶联制备,并为评估我们方法的潜在效用提供了基准。

  • Soluble late transition metal catalysts for olefin oligomerizations III
    申请人:Zhao Baiyi
    公开号:US20060036049A1
    公开(公告)日:2006-02-16
    A series of soluble α-diimine late transition metal catalysts has been invented comprising a substituted or unsubstituted catecholate ligand. The catalysts demonstrate high activity and selectivity for linear α-olefins. As such, these catalysts conveniently oligomerize ethylene. Typical activators as known to those of ordinary skill in the art are used to activate these transition metal catalysts. These catalysts can be used in a supported or unsupported form.
    一系列可溶性的α-二亚胺后过渡金属催化剂已经被发明,其中包括取代或未取代的邻苯二酚配体。这些催化剂表现出高活性和线性α-烯烃的高选择性。因此,这些催化剂方便地可以使乙烯寡聚化。通常的活化剂,如对于普通技术人员而言是已知的,被用来激活这些过渡金属催化剂。这些催化剂可以以支持或不支持的形式使用。
