Free Radical Hydrophosphorylation of Fluoroalkyl Vinyl Ethers: Synthesis of Fluoroalkyl Phosphonates

Abstract: An effective method for the synthesis of dialkyl [2-(polyfluoroalkoxy)ethyl]phosphonates by free radical hydrophosphorylation of fluoroalkyl vinyl ethers with dialkyl (H)-phosphonates was developed. The reaction proceeds in the presence of catalytic amounts of azabisisobutyric acid dinitrile (AIBN) (150°C, 2 h, portionwise addition of AIBN) to afford the target fluoroalkyl phosphonates in up to 85% isolated yield.

SYNTHESIS AND SOME PROPERTIES OF THE VINYL ETHERS OF POLYFLUORINATED ALCOHOLS

The vinylation of polyfluoroalkanols by acetylene under pressure was investigated with various catalysts (cadmium acetate, potassium alkoxides and hydroxide).In the presence of basic catalysts, irrespective of the reaction conditions, the yield of the fluorovinyl ethers is not greater than 5-12percent.In the presence of cadmium acetate the yield of the ethers is 50-64percent.The effect of various factors (solvents, amount of catalyst, complexing additives, reaction time) on the degree of reaction is discussed.The vinyl ethers of polyfluorinated alcohols do not exhibit anomaliesin the reactions with carbixylic acids, alcohols, and thiols.
