Abstract: An alkoxyvinyl ether is disclosed having the chemical structure RfC(OR)═CHRf′, wherein Rf is an at least partially fluorinated functional group having at least one carbon atom, Rf′ is an at least partially fluorinated functional group having at least two carbon atoms, and R is a functional group. A method for preparing an alkoxyvinyl ether is disclosed, comprising RfCFHCFHRf′+KOH/ROH→RfC(OR)═CHRf′, wherein Rf is a perfluoro functional group, Rf′ is a perfluoro functional group, and R is an alkyl functional group. Another method for preparing an alkoxyvinyl ether is disclosed, comprising RfCF═CHRf′+KOH/ROH→RfC(OR)═CHRf′, wherein Rf is a perfluoro functional group, Rf′ is a perfluoro functional group, and R is an alkyl functional group.
