  镍催化炔烃加氢立体发散合成E-和Z-烯烃

  摘要：

  开发了一种使用镍催化剂将炔烃立体发散氢化为E-和Z-烯烃的便捷方案。简单的Ni(NO 3 ) 2 ⋅6 H 2 O作为催化剂前体形成活性纳米粒子，可有效地对多种炔烃进行半加氢，并且对Z-烯烃具有高选择性（ Z / E > 99:1）。添加特定的多齿配体（三磷、四磷）后，所得分子催化剂对E-烯烃产物具有高度选择性（E/Z > 99:1）。机理研究表明Z-烯烃选择性催化剂是非均相的，而E-烯烃选择性催化剂是均相的。在后一种情况下，炔烃首先被氢化为Z-烯烃，随后异构化为E-烯烃。该提议得到了密度泛函理论计算的支持。这种合成方法被证明普遍适用于超过 40 个例子，并且可扩展到多克规模的实验。

• C3‐Cyanation of Pyridines: Constraints on Electrophiles and Determinants of Regioselectivity
  作者：Ming Zhang、Qingyang Zhou、Heng Luo、Zi‐Lu Tang、Xiufang Xu、Xiao‐Chen Wang

  DOI：10.1002/anie.202216894

  日期：2023.2

  C3-selective cyanation of pyridines was accomplished by a tandem process of borane-catalyzed pyridine hydroboration, substitution of the resulting dihydropyridine with a cyano electrophile, and finally oxidative aromatization. This method was suitable for use in late-stage cyanation of pyridine drugs.

  吡啶的 C3 选择性氰化是通过硼烷催化的吡啶硼氢化、用氰基亲电试剂取代所得二氢吡啶、最后氧化芳构化的串联过程完成的。该方法适用于吡啶类药物的后期氰化反应。
