✦ Synopsis

Fluoroalkylethylenes of types 1 and 2 are unresponsive to the usual reagents for epoxidation, but recent methods have made the epoxides and related halohydrins readily available. Use of the reagent Xs/nSOs, which readily attacks the double bond of both 1 and 2, will be described in detail and compared to two other effective reagents. Halohydrins of 1 and 2 are readily obtained and converted to epoxides 3 and 4, the latter of which is a previously unknown class. RrCH=CHs RFCH=CHRF RF?"?~ RrCHCHRF 1 2 0 '0' 3 4

Some chemistry of the intermediates and epoxides, including polymerization, will also be presented.
