Amines, Imines, Cyanides, Isocyanides, and Isocyanates

Nitrogen.—Amines, Imines, Cyanides, Isocyanides, and Isocyanates. Information relating to the application of FC-43 [(C4F,)aN] and other fluorocarbon-type liquids as oxygen-transport agents in artificial blood continues to mount. °° The advances made are also being reported in the popular

The tertiary amines (23)—(25) are produced, together with perfluoro-AW-bipiperidyl (26) and the fluorocarbons (CF,),CF CF(CF,), and (CF,) CF. CFi-CFi-CFs, when perfluoro-iV-fluoropiperidine is subjected to u.v. radiation in the presence of p uoropropene presumably the reaction proceeds via a free-radical sequence of the type proposed to explain the outcome of a similar conversion involving perfluorocyclobutene (initiation step  

Reinvestigation of the CsF-initiated autoclave reaction between perfluoro-AT-fluoropiperidine and perfluoropropene at elevated temperatures has shown that the product formerly believed to be petfluoro-( -iso-propylpiperidine) (24), and formed via the 5n2 process 

Recent work on the fluorinationof aromatic substrates (see p. 3S2) is discussed in terms of electron transfer reactions, as was the reductive de fluorination of perfluorinated N—F compounds with ferrocene or dicumene-
