fluorination due to the presence of bulky N-alkyl group was not observed as a result of the ECF of these aliphaticsecondaryamines. It was also found that the change of the initial solute concentration of N,N-di-n-propylamine did not affect on the product yields, which is usually observed for cyclic secondaryamines. Several F-(N-fluoro-N,N-dialkylamines) were treated with triphenylphosphine for conversion into
A conducting polymer having photochromic diarylethene units in the main chain was synthesized. Reversible photochromism was observed in solid film, and photoluminescence and electrical conductivity were found to change along with the photoisomerization.

Described herein is an hydrofluorocarboximidate of formula (I) where: RH is a linear or branched alkyl group comprising 1 or 2 carbon atoms and (a) Rf1 and Rf2 are independent-selected from a linear or branched perfluorinated alkyl group comprising 1-8 carbon atoms and optionally comprising at least one catenated atom selected from oxygen, nitrogen, or combinations thereof; or (b) Rf1 and Rf2 are connected to form a ring structure comprising a total of 4-8 carbon atoms and in addition to the nitrogen atom from the carboximidate the ring structure may optionally comprises at least one catenated atom selected from oxygen, nitrogen, or combinations thereof. A method of making the hydrofluorocarboximidate with improved yield is described as well as various uses for the hydrofluorocarboximidate of Formula (I).
