摘要：

The new compound ClO2SCF2CF2SO2Cl (1) is prepared by oxidative cleavage of the S-S bonds in the cyclic polysulfides <(CF2CF2S3,4)over bar>, with chlorine and hydrogen peroxide. Compound (1) is converted in high yield to the bis(fluorosulfonyl) tetrafluoroethane FSO2CF2CF2SO2F (2) by reaction with KF. This work represents an attractive alternative to the previously reported preparation of (2) by electrochemical fluorination (ECF). (C) 1998 Elsevier Science S.A. All rights reserved.
