Fluorinated aldehydes are made by reacting a fluorinated acyl chloride with a silicon hydride in the presence of palladium. Also disclosed are fluorinated ether aldehydes and their polymers, a process for making fluorinated aldehydes polymers using titanium or aluminum alkoxide catalysts, and a process for endcapping fluorinated polymers using perfluoroallyl fluorosulfate or fluorine.

A process for manufacturing a polyfluroalkanoyl phosphorodichloridate comprising reacting a polyfluoroalkanol having the general formula Rf-CH2-OH, wherein Rf is a linear or branched C1-C8 perfluoroalkyl group optionally interrupted by O, with at least 4 moles of POCI3 per mole of Rf-CH2-OH in the presence of 0.1 to 0.2 moles of LiCI catalyst per mole of Rf-CH2-OH at a temperature between 95°C and 110°C to form a phosphorodichloridate of the general formula Rf-CH2-O-P(O)Cl2.
