本文报告三氧化硫和氯三氟乙烯的加合反应,以及由此而得的一衍生物。各种定量分析、化学反应和光谱结果指示最合理结构是一个四员杂环的β-磺内酯(Ia+Ib)。对于这一个衍化物的化学性能,也作了初步的研究。

同样的,从液体三氧化硫与4,5-二氯全氟戊烯-1、4,6,7-三氯全氟庚烯-1、4,6,8,9-四氯全氟壬烯-1、4,6,8,10,11-五氯全氟十一烯-1的加合反应产物内,经分馏后也可以得到颇为纯粹的同类衍化物(β-磺内酯),产率为70-80%。4,4-二氯全氟丁烯-1以及2,3-二氯全氟丁烯-2与三氧化硫反应后所得的产物则不甚纯净;1,2-二氯二氟乙烯以及全氟丙烯与三氧化硫的反应产物则更不纯净。

An addition product which is very likely a,Q-sultone vas obtained from the spontaneous reaction between chlorotrifluoroethylene and sulfur trioxide as a distillable colorless liquid (Ia+Ib; b.p.76.0-76.5°,nD20° 1.3672, d21.8° 1.71).Its structure was elucidated by elementary analysis, determinations of molecular weight and saponification equivalent, and its infrared spectrum.Preliminary studies of its chemical behavior are also here reported.
