ic acid (1) was prepared using a new procedure starting from perchloromercaptan, which is readily obtained from chlorination of CS2. Modified Swarts reaction transformed N,N-diethyl trichloromethanesulfenamide into N,N-diethyl chlorodifluoromethanesulfenamide, and the latter species was further oxidized and hydrolyzed into chlorodifluoromethanesulfonic acid. The preparations of other two new α,α-d
氯二氟甲磺酸(1)是使用新的方法从全氯硫醇开始制备的,而全氯硫醇可从CS 2的氯化反应中轻松获得。改进的Swarts反应将N,N-二乙基三氯甲烷亚磺酰胺转化为N,N-N-二乙基氯二氟甲烷亚酰胺,后者被进一步氧化并水解为氯二氟甲烷磺酸。还公开了另外两种新的α,α-二氟链烷磺酸,苯基二氟甲磺酸(2)和2-苯基-1,1,2,2,-四氟乙烷磺酸(3)的制备。酸2和3以钠(锂)盐形式或在水溶液中稳定;但是,2和3的纯形式可以很容易地进行脱氟。1 - 3和它们的盐具有潜在的应用作为超强酸催化剂和锂电池电解质。
