The strategy of searching for highly electrophilic agents in a class of chemically inert compounds-methylenequinone imines-was developed and successfully performed. The first representative of such electrophiles -N-acyl-alpha-methoxycarbonyl-alpha-trifluoromethyl-p-methylenequinone imine 6-was synthesized. Its reactions with N-, O- and C-nucleophiles were investigated that gave various derivatives of alpha-trifluoromethyl-a-amino(oxy) acids as well as beta,beta,beta-trifluoropropionic acids. 3-Chloro-3-trifluoro-1,3-dihydroindol-2-ones were first obtained and their reactions with nucleophiles were studied with 1-aza-3-trifluoroindene-2-ones being formed as intermediates.
