title: Nucleophilic substitution and Claisen rearrangement reactions of model fluoroalkenes of general structure R-CF=CF-CF3.
abstract: Fluoroalkenes of general structure R-CF=CF-CF3 (2a, R = cyclopentyl and 2b, R = cyclohexyl), prepared in high yield in two steps from hexafluoropropene and the appropriate cycloalkane, react with oxygen, carbon, and hydrogen nucleophiles to give R-CX=CF-CF3 derivatives (X = H, OR, R, Ar). Reaction of fluoroalkenes 2a and 2b with allylic alkoxides gave products arising from Claisen rearrangement, providing access to keto-alkenes bearing >CFCF3 units in mid-aliphatic chain positions.
