2,3,3-Trifluoro-l-pmpenyl p-chlorobenzenesulfonate (1), readily available from 2,2,3,3tetrafluoropmpanol, reacted smoothly with various Grignard reagents at 50 °(3 to afford the corresponding (Z)-a, fl-difluoroallyl alcohols 2 in moderate to excellent yields. These alcohols were smoothly hydrolyzed
