    摘要: Tris(dialkylamino)sulfonium bifluoride salts are obtained by hydrolysis, methanolysis, or pyrolysis of corresponding tris(dialkylamino)sulfonium difluorotrimethylsilicates, reaction of dialkylaminotrialkylsilanes with sulfur tetrafluoride, or reaction of bis(dialkylamino)sulfur difluorides with dialkylamines. These bifluoride salts, which have the general formula (R.sup.1 R.sup.2 N)(R.sup.3 R.sup.4 N)(R.sup.5 R.sup.6 N)S.sup..sym. HF.sub.2.sup..crclbar., are useful polymerization catalysts.

    摘要: 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.
