non‐nucleophilic substrates using α‐carbonyl sulfoxonium ylides has not been so far investigated, despite the potential safety advantages that such reagents would provide over either diazo compounds or their in situ precursors. Described herein are the cross‐coupling reactions of sulfoxonium ylides with C(sp2)−H bonds of arenes and heteroarenes in the presence of a rhodium catalyst. The reaction proceeds by a succession
迄今为止,尚未研究过使用α-羰基sulf基亚砜在非亲核底物中的碳氢键功能化,尽管这种试剂比重氮化合物或其原位前体具有潜在的安全优势。本文描述的是在铑催化剂存在下,亚砜基鎓与芳烃和杂芳烃的C(sp 2)-H键的交叉偶联反应。反应通过连续的C–H活化,叶立德向碳-金属键的迁移插入以及原金属的脱金属而进行,最后一步是限制营业额。该方法适用于与铱催化的脱水环化反应相关的苯并[c] ac啶的合成。
