Synthese d'ethers et de thioethers allyliques fluores par catalyse par transfert de phase

Abstract

Several fluorinated allylic ethers, thioethers and diethers have been prepared in excellent yields by phase transfer catalysis (CTP). The used halogenated compounds are allyl chloride and bromide, p-chloromethylstyrene. The used fluorinated alcohols are aromatic pentafluorophenol and various aliphatics: CF 3CH 2OH, CF 2HCF 2CH 2OH ClCF 2CF 2CH 2OH,C 6F 13C 2H 4OH, HOCH 2CF 2CFClCF 2CH 2OH and HOC 6H 4C(CF 3) 2C 6H 4OH. All these new compounds have been characterized by 1H and 13C NMR. We conclude that CTP is the best method to obtain allylic and diallylic compounds.
