Allyl alcohol and allyl alcohol containing the polyoxyethylene unit were found to react with fluoroalkanoyl peroxides to afford the corresponding fluoroalkylated allyl alcohol oligomers via a radical process under very mild conditions. In particular, fluoroalkylated allyl alcohol oligomers containing the polyoxyethylene unit were shown to be effective in reducing the surface tension of water, and to be applicable for new non-ionic fluorinated amphiphiles.
