摘要
The fluorination of N-substituted carbamates was shown to be a general method for the synthesis of difluoramino compounds and substituted fluorocarbamates. Substituents included alkyl and cycloalkyl groups as well as alkyl groups containing ester, nitro, or nitramino groups. The fluorination of carboalkoxyguanidines gave carboalkoxytetrafluoroguanidines, and the fluorination of 1,3-dicarboalkoxyguanidines gave carboalkoxytetrafluoroguanidines as well as 1,3-dicarboalkoxytrifluoroguanidines. 1-Carbethoxy-3-cyanoguanidine gave carbethoxytetrafluoroguanidine, ethyl N-(difluoraminodifluoromethyl)-N-fluorocarbamate, and ethyl N-(fluoriminofluoromethyl)-N-fluorocarbamate. © 1969, American Chemical Society.
