1,2‐Boron ate rearrangements represent a fundamental class of transformations to establish new C−C bonds while retaining the valuable boron moiety in the product. In established ionic processes, the boron ate complex is activated by an external electrophile to induce a 1,2‐migration from boron to an adjacent sp ³ or sp ² carbon atom. Recently, two complementary radical polar crossover approaches have been explored for both classes, 1,2‐migrations to sp ² and sp ³ carbon centers. This review describes the general concepts in this emerging research field and summarizes recent developments of radical‐induced 1,2‐migrations from boron to carbon.

硼络合物的自由基诱导 1,2-迁移。

1,2-硼酸重排代表了一类基本的转变，可建立新的 C−C 键，同时保留产物中有价值的硼部分。在已建立的离子过程中，硼酸盐络合物被外部亲电子试剂激活，诱导从硼到相邻的sp ³或sp ²碳原子的 1,2-迁移。最近，两种互补的自由基极性交叉方法已被探索用于两类，1,2-迁移到sp ²和sp ³碳中心。这篇综述描述了这个新兴研究领域的一般概念，并总结了自由基诱导的从硼到碳的 1,2-迁移的最新进展。
