Conselho Nacional de Desenvolvimento Científico e TecnológicoThis work, at first, describes the synthesis and characterization of new series of (Z,Z)-N,N -bis(oxotrifluoroalkenyl)-1,3-phenylenediamines by the addition/elimination reaction of β-alkoxyvinyl trifluoromethyl ketones with 1,3-phenylenediamine, in 47-91 % yields. The 4-alkyl[aryl(heteroaryl)]-4-alkoxy-1,1,1-trifluoro-3-alken-2-ones, of general formula F3C-C(O)-CH=C(R1)-OR where R = Me, Et and R1 = H, Me, Ph, 4-MePh, 4-OMePh, 4-ClPh, 4-FPh, 4-BrPh, 4-NO2Ph, 2-furoyl, 2-thienyl, were obtained from trifluoroacetylation reactions of enolethers or acetals derived of acyclic ketones. Subsequently is reported the synthesis and characterization of new series of bis-trifluoromethyl substi...
