Methods of producing N,N-branched sulfamoyl fluoride compounds of the formula F-S(O)2-NR2 by contacting bismuth trifluoride with an N,N-branched sulfamoyl nonfluorohalide compound of the formula X-SO2NR2, wherein X = chlorine (C1), bromine (Br), or iodine (I), and each R is, independently, a linear or branched alkyl, fluoroalkyl, alkenyl, fluoroalkenyl, alkynyl, or fluoroalkynyl with 1 to 12 carbon atoms, to fluorinate the N,N-branched sulfamoyl nonfluorohalide compound. This is a non-aqueous method, the purity of product is very high, and the desired product can be isolated in quantitative yield. The N,N-branched sulfamoyl fluoride compounds so produced are useful in various applications including as electrolyte solvents and additives in electrochemical devices, such as lithium batteries and capacitors, and in biological fields, among others.
通过将三氟化铋与公式为X-SO2NR2的N,N-分支磺酰非氟卤化合物接触,其中X = 氯(Cl),溴(Br)或碘(I),每个R独立地是具有1至12个碳原子的线性或分支烷基,氟烷基,烯基,氟烯基,炔基或氟炔基,以氟化N,N-分支磺酰非氟卤化合物,从而制备公式为F-S(O)2-NR2的N,N-分支磺酰氟化物化合物的方法。这是一种非水方法,产品纯度非常高,所需产品可以以定量收率分离。因此制备的N,N-分支磺酰氟化物化合物在各种应用中非常有用,包括作为电解质溶剂和电化学器件中的添加剂,例如锂电池和电容器,以及在生物领域中等。
