Conventional visible-light-induced Smiles rearrangements generate C, N, or O radicals and release SO2. Herein, we describe a perfectly atom-economical protocol for Smiles rearrangements without release of SO2. The protocol not only afforded alkyl sulfinic acid salts via photocatalyzed radical addition, aryl migration, and sulfone radical reduction but also permitted efficient functionalization of butenyl
常规可见光诱导的微笑重排产生 C、N 或 O 自由基并释放 SO 2。在这里,我们描述了一个完美的原子经济协议,用于微笑重排而不释放 SO 2。该协议不仅通过光催化自由基加成、芳基迁移和砜自由基还原提供了烷基亚磺酸盐,而且还允许在温和条件下对丁烯基杂芳基砜衍生物进行有效功能化。
