A number of β-ethoxyvinyl polyfluoroalkyl ketones were synthesized by acylation of ethyl vinyl ether with acid chlorides containing polyfluoroalkyl groups of different composition and structure. Some typical nucleophilic reactions of the title compounds with amines were carried out. Two new fluoro-containing pyrimidinoles were synthesized by the reaction of β-ethoxyvinyl polyfluoroalkyl ketones with urea.
The reaction of iminium triflates 2 and 7 with various aromaticamines were investigated. The 2-Rf-substituted quinolines 3 and 8 were prepared in excellent yields by the reaction of 2 and 7, respectively, with substituted anilines. The reactions of 2 and 7 with diarylamines proceeds, suprisingly, to afford the corresponding 3-Rf-substituted cinnamaldehydes 4 and 9.
