Classic Brook rearrangements via anionic migration of silyl groups are employed extensively in the transformation of organosilicon compounds. However, radical-mediated Brook rearrangements remain underexplored. In this issue of Chem Catalysis, Shen and co-workers disclose an organophotocatalytic 1,2-Brook rearrangement to efficiently provide allyl tert-(hetero)cyclobutanols and investigate their subsequent ring-opening and -expansion functionalizations.

自由基介导的 1,2-布鲁克重排

通过甲硅烷基的阴离子迁移进行的经典布鲁克重排广泛用于有机硅化合物的转化。然而，自由基介导的布鲁克重排仍未得到充分探索。在本期Chem Catalysis 中，Shen 及其同事公开了一种有机光催化1,2-Brook 重排，可有效提供烯丙基叔-（杂）环丁醇并研究其随后的开环和扩环功能化。
