磺酰腙是一种特殊类型的磺化腙，近期被开发用作新的 C-H 官能化的 C1 或 C2 合成子，以通过形成金属碳烯物质，从而接近酰基甲基化或环化化合物。有很多杰出的工作报道，可通过这些万能的合成子合成各种有用的分子骨架。此前，这些开发工作未被全面的调查或综述。本综述中，我们对 α-羰基磺酰腙用于 C-H 官能化的最新进展进行了汇总，其中包括其在 ortho-C–H 酰基甲基化反应和在 ortho-C–H 活化/环化反应中的应用。

Sulfoxonium ylides are a special type of sulfur ylides that serve as new C1 or C2 synthons recently developed for use in C–H functionalization to access acylmethylated or cyclized compounds through the formation of metal carbene species. Many excellent works have reported the syntheses of various useful skeletons from these versatile synthons. These developments have not previously been completely investigated or reviewed. In this review, we summarize recent advances in the use of α-carbonyl sulfoxonium ylides in C–H functionalizations, including ortho-C–H acylmethylation reactions and ortho-C–H activation/cyclization reactions.
