demonstrated through the unprecedented reaction with diazo compounds. The chemoselective hydro- and chloropentafluorosulfanylations of α-diazo carbonyl compounds were developed in the presence of K3PO4 or copper catalyst, respectively. These reactions provide a direct and efficient access to various α-pentafluorosulfanyl carbonyl compounds of high value for potential applications.
五氟硫酰氯 (SF 5 Cl) 是将 SF 5基团结合到有机化合物中的最常用试剂。然而,SF 5 Cl的制备通常依赖于危险的试剂和专门的仪器。在本文中,我们描述了一个台架稳定的安全和实用的合成和SF的易于手柄溶液5在含Cl Ñ正己烷气体试剂-自由条件下进行。SF 5 Cl的合成应用通过与重氮化合物的前所未有的反应得到证明。在 K 3 PO 4存在下开发了 α-重氮羰基化合物的化学选择性氢和氯五氟磺基化反应或铜催化剂,分别。这些反应为获得各种具有高价值的 α-五氟硫基羰基化合物提供了直接有效的途径,可用于潜在应用。

trans-Trifluoromethyltetrafluorosulfanyl chloride (trans-CF3SF4Cl) is a unique reagent for the incorporation of the CF3SF4 group into organic compounds. However, CF3SF4Cl was prepared from hazardous reagents or formed as mixture of trans and cis isomers in low yield. Herein, a silver-promoted selective synthesis of trans-CF3SF4Cl under safe gas-reagent-free conditions is described. Furthermore, the
反式-三氟甲基四氟硫基氯(反式-CF 3 SF 4 Cl)是将CF 3 SF 4基团结合到有机化合物中的独特试剂。然而,CF 3 SF 4 Cl是由危险的试剂制备的或形成为低收率的反式和顺式异构体的混合物。在此,描述了在安全无气体试剂的条件下银促进的反式-CF 3 SF 4 Cl 选择性合成。此外,反式-CF 3 SF 4的合成应用Cl 通过 α-重氮羰基化合物的新三氟甲基四氟硫烷基化得到证明。
