, 73. THE SYIVl?HESIS OF FLUORAMMONIUM SALTS’ Vytautas Grakauskas, Allen H. Remanick, and Kurt Baum Contribution from Chemical & Biological Processes, Aerojet.-General Corporation, Azusa, California 91703. Of the four possible fluorine-substituted ammonium ions, only the tetrafluoro derivative has been reported as a stable salt.*,3 Difluoramine and trifluoramine have been reported to form reversible complexes with Lewis acids at low Lenperatures. Fluoramin was claimed to be a by-product of the electrolysis of ammonium bifluoride5~‘ but the results have been shown to be in error.7 Xnethylfluoramihe was synthesized by the fluorination of unsymmetrical dimethylsulfamide and the compound was sufficiently basic to form a stable hydrochloride. Fluorimonium salts prepared by the rearrangement of aikyldifluoraainesg can also be considered as alkylidene derivatives of substituted fluoramines. 8 Simple salts of fluoramine have now been prepared by the reaction of alkyl N-fluorocarbamates with strong acids. The starting materials are synt’iesized readily by the fluorination .of alkyl carbamates.1° Fluoraomonim Bisulfate. Fluorimonium salts have been prepared and cnaracterizea in sulfuric acid. Under these conditions, the hydrolysis of N- fluorocarbamates in sulfuric acid would be expected to give the fluorammonium ion, which also should be stable. !;%en a solition of ethyl N-fiuorocarbamate in concentrated sulfuric acid bas heated at 65 to 4G0, carbon dioxide and ethylene were evolved. The F13 nm spectrum of the sulfuric acid solution consisted of a quartet at 36.8 ppm relative to SLternai trifluoroacetic acid, with a coupling constant of 38 cps. ?nus, the flmrine was coupled to three equivalent hydrogens, and it is notexorthy that tne hydrogens did not exchange rapidly with the solvent. By contrast, the F19 spectrum of an unheded solution of ethyl N-fluorocarbamate in sulPaic acid consisted of a single broadened signal at 27.5 ppm; the NH protons of the starting material thus exchanged with the solvent rapidly by the nmr time scale.
