近年来,过渡金属催化的C—H键官能团化反应引起了广泛的关注并得到迅速发展.作为一个不可替代的合成子,异腈已被广泛应用于合成各类含氮杂环化合物.本综述介绍了异腈参与的惰性键活化反应的最新研究进展及其在有机合成中的应用,包括异腈对C—H键或N—H键的插入反应以及异腈参与的自由基氧化成环反应等. In recent years, the transition metal-catalyzed C-H bond functionalization has attracted widespread attention and has been rapidly developed.As an irreplaceable synthetic, isonitrile has been widely used in the synthesis of various nitrogen-containing heterocyclic compounds. Recent advances in the activation of inert bonds involving isonitriles and their applications in organic synthesis were introduced, including the insertion of isonitriles into C-H bonds or N-H bonds and the radical oxidation of isonitriles to ring-forming reactions Wait.
