Carbonylfluoride is a versatile intermediate to organic fluorine compounds. Its reaction with carbonyl compounds such as cyclohexanone, benzaldehyde and benzophenone gives the gem-difluorides, while N,N-dimethylformamide yields a,a-difluorotrimethylamine. Metal fluoride-catalyzed addition at the ethylenic bond in perfluoroolefins forms perfluoroacyl fluorides, while the C--?! unsaturated compounds
The electrochemical fluorination of nitrogen-containing carboxylic acids. Fluorination of dimethylamino- or diethylamino-substituted carboxylic acid derivatives
The electrochemical fluorination of six derivatives of dimethylamino- or diethylamino-substituted carboxylicacids has been conducted. As the main fluorination products, cyclized and cleaved products as well as the desired N-containing perfluoroacid fluorides were formed, and their ratios depended on the chain length and the structure of the starting carboxylicacids, and the nature of the dialkylamino
Nine perfluoroacylfluorides underwent halogen exchange when treated with anhydrous lithium halides to give acyl chlorides, bromides and iodides in high yields. The temperature dependence of this reaction is described. In the reaction with perfluorodiacyl fluoride, the diacyl halides possessing different acyl halide-groups were also produced. Of the alkaline metal salts used halogen exchange was successful

The first N-containing trifluorovinyl ether monomer (CF3)2NCF2OCFCF2 was synthesized. The starting perfluoroalkyl imine CF3–NCF2 was converted to the perfluoroalkyl amine (CF3)2NH by HF. The amine was converted into the carbamoyl fluoride (CF3)2NC(O)F via reaction with carbonyl fluoride COF2 in the presence of NaF. The carbamoyl fluoride was subjected to catalytic fluorination with molecular F2 in
