Pyry-BF4
结构式
基本信息
| Empirical Formula【经验(实验)分子式】 | C5H5BF4O |
| Molecular weight | 167.90 |
| Application【应用】 | Pyrylium tetrafluoroborate is used for the functionalization of heterocyclic amines, activating them for nucleophilic substitution. As demonstrated by the Cornella lab, the intermediate pyridinium salts can react with a vast array of nucelophiles to form new C-N, C-O, and C-S bonds, making pyrylium tetrafluoroborate a valuable reagent for late-stage functionalization. |
| Other Notes【其他说明】 | Selective Functionalization of Aminoheterocycles by a Pyrylium Salt Selective Late-Stage Sulfonyl Chloride Formation from Sulfonamides Enabled by PyryBF4 Synthesis of Sulfonyl Fluorides from Sulfonamides |
