一般說明

二氟甲烷亚磺酸锌是广泛用于将二氟甲基官能团结合到生物学上重要的结构基序上的一种试剂。它可用于二氟甲基化一些化合物，例如杂芳烃、硫醇、烯酮和 α、 β不饱和羧酸。
材料与最多 1 当量的氯化锌络合

應用

二氟甲烷亚磺酸锌 (DFMS) 是 Phil Baran 开发的亚磺酸锌工具箱的一部分，用于杂环的简单快速多样化。†

杂环化合物的实用固有碳氢功能化

DFMS 是一种新型的有机底物自由基直接二氟甲基化试剂。这种温和、操作简单、化学选择性和可放大的二氟甲基化方法与一系列不同复杂程度的含氮杂芳烃底物以及选择的共轭 p-系统和硫醇类相容。†

Sulfinic acids and their salts have recently emerged as versatile coupling partners to efficiently access a wide variety of hetero- and carbocyclic compounds, under relatively mild conditions. Their growing importance is attributable to their dual capacity for acting as nucleophilic

Journal of the American Chemical Society, 134(3), 1494-1497 (2012-01-11)
Molecular scaffolds containing alkylfluorine substituents are desired in many areas of chemical research from materials to pharmaceuticals. Herein, we report the invention of a new reagent (Zn(SO(2)CF(2)H)(2), DFMS) for the innate difluoromethylation of organic substrates via a radical process. This

Radical addition processes can be ideally suited for the direct functionalization of heteroaromatic bases, yet these processes are only sparsely used due to the perception of poor or unreliable control of regiochemistry. A systematic investigation of factors affecting the regiochemistry

Nitrogen-rich heterocyclic compounds have had a profound effect on human health because these chemical motifs are found in a large number of drugs used to combat a broad range of diseases and pathophysiological conditions. Advances in transition-metal-mediated cross-coupling have simplified

The synthesis of heteroaromatic and aromatic compounds is at the heart of the chemical industry. The ever-growing demand for new chemical entities, coupled with dwindling resources and time constraints allotted to any given research project, a rapid way to diversify (hetero)aromatic scaffolds is needed.
