Popis: | Fluorocarboethoxymethylene tri-n-butylphosphorane, Bu3P=CFCOOEt (3), reacts with per- and poly-fluoroalkyl-substituted carboxylic acid esters, ethyl formate and γ-butyrolactone to give the corresponding enol ethers, RFC (OEt)=CFCOOEt (4), in good yield. Non-activated esters failed to react with 3. With the anion derived from ethyl diethylphosphonofluoroacetate, (EtO)2P(O)CFHCOOEt (5), a mixture of 4 and β-ketoesters, RFC(O)CFHCOOEt (7), is formed. |
