trialkylamines in liquid HF takes place readily in good yields, whereas dialkyl ethers give low yields. The latter fluorinated ethers are of interest for their low temperature properties. Our goal in this work was to prepare fluorinated aminoalkylether fluids which might combine the favorable yields of amines and properties of ethers. Several dialkylamine and alkylene units were combined in a variety of diamino
Six methyl esters of 3-dialkylamino-substituted propionic acids were subjected to electrochemicalfluorination to give the corresponding perfluoroacid fluorides. The following dialkylamino substituents were investigated: diethylamino, di-n-propyl-amino, di-n-butylamino, pyrrolidino, morpholino and piperidino groups. These perfluoroacid fluorides, which were obtained in fair yields, are considered to
将3-二烷基氨基取代的丙酸的六种甲酯进行电化学氟化,得到相应的全氟代氟化物。研究了以下二烷基氨基取代基:二乙基氨基,二正丙基氨基,二正丁基氨基,吡咯烷基,吗啉代和哌啶子基。这些以合理收率获得的全氟酸氟化物被认为是制备软质(可降解)含氟化合物的潜在关键前体。这些盐在水溶液中显示出明显降低的表面张力。报告了所获得的所有全氟酸氟化物的物理性质,以及它们的光谱数据(19 F NMR,质谱和IR光谱)。

(EN) A process for preparing tertiary perfluoroamines is provided. The process comprises electrochemically fluorinating a tertiary thioamide precursor, said thioamide precursor having at least one thioamide moiety, see formula (I), and terminal portions which can be alkyl or cycloalkyl having 1 to 12 carbon atoms, aryl having 6 to 12 carbon atoms, or combinations thereof, with the proviso that when more than one thioamide moiety is present, the thioamide moieties are bonded together by alkylene, cycloalkylene or arylene groups. Also provided are tertiary thioamides and tertiary perfluoroamines.(FR) Procédé de préparation de perfluoroamines tertiaires. Le procédé consiste à fluorurer électrochimiquement un précurseur de thioamide tertiaire, ledit précurseur de thioamide ayant au moins une fraction thioamide, cf formule (I), ainsi que des parties terminales pouvant être alkyles ou cycloalkyles contenant 1 à 2 atomes de carbone, aryle contenant 6 à 12 atomes de carbone ou des combinaisons de ceux-ci, à condition que lorsque plus d'une fraction thioamide est présente, les fractions thioamide soient liées ensemble par des groupes alkylène, cycloalkylène ou arylène. L'invention concerne également des thioamides tertiaires ainsi que des perfluoroamines tertiaires.
