The development of protocols catalyzed by main group element compounds is desirable to substitute rare and toxic transition metal catalysts. In this issue of Chem, Melen and co-workers employ B(C₆F₅) as a catalyst for the reaction of α-aryl-α-diazoesters with different heterocycles giving high selectivities and yields in a variety of transformations.

α-重氮酸酯与杂环和烯烃的选择性B（C ₆ F ₅）₃催化反应

需要开发由主族元素化合物催化的方案，以替代稀有和有毒的过渡金属催化剂。在本期《化学》杂志中，梅伦（Melen）和同事使用B（C ₆ F ₅）作为催化剂，使α-芳基-α-重氮酸酯与不同的杂环反应，从而在各种转化中具有较高的选择性和收率。
