  Iridium-Catalyzed X−H Insertions of Sulfoxonium Ylides

  摘要：

  The unique reactivity of sulfoxonium ylides as a carbene source is described for a variety of X-H bond insertions, taking advantage of a simple, commercially available iridium catalyst. This method has applications in both intra- and intermolecular reactivity, including a practical ring-expansion strategy for lactams. The safety and stability of sulfoxonium ylides recommend them as preferable surrogates to traditional diazo ketones and esters.

  The first straightforward strategy for the synthesis of 1,4-dicarbonyl Z-alkenes has been developed via an electrochemical cross-coupling reaction of sulfoxonium ylides and alkynes with water. The metal-free protocol showed an easy-to-handle nature, good functional group tolerance, and high Z-stereoselectivity, which is rare in previous cases. The proposed reaction mechanism was convincingly established

  合成 1,4-二羰基Z-烯烃的第一个直接策略是通过亚砜叶立德和炔烃与水的电化学交叉偶联反应开发的。无金属方案表现出易于处理的性质、良好的官能团耐受性和高Z-立体选择性，这在以前的案例中是罕见的。通过进行一系列控制实验、循环伏安实验和密度泛函理论（DFT）研究，令人信服地建立了所提出的反应机理。
