Cyano group as a versatile functionalized intermediate has been explored for several decades, as it readily transfers to many useful functionalization groups such as amine, amide, acid, etc., which make it possess high popularization and use value in organic synthesis. Reactions involved with element-cyano bond cleavage can provide not only a new cyano group but also a freshly functionalized skeleton in one-pot, consequently making it of high importance. The highlights reviewed herein include H-CN, Si-CN, C-CN, B-CN, Sn-CN, Ge-CN, S-CN, Halo-CN, N-CN, and O-CN bonds cleavages and will summarize progress in such an important research area. This review article will focus on transition metal catalyzed reactions involving element-cyano bond activation.

过渡金属催化元素氰键活化。

氰基作为通用的功能化中间体已被探索了数十年，因为它可以轻松转移到许多有用的官能团上，例如胺，酰胺，酸等，使其在有机合成中具有很高的推广和使用价值。与元素-氰基键裂解有关的反应不仅可以提供一个新的氰基，还可以在一个锅中提供一个新鲜的官能化骨架，因此使其具有很高的重要性。本文重点介绍了H-CN，Si-CN，C-CN，B-CN，Sn-CN，Ge-CN，S-CN，Halo-CN，N-CN和O-CN键断裂的情况，并将总结在如此重要的研究领域取得进展。本文将重点介绍过渡金属催化的涉及元素氰基键活化的反应。
