Abstract
The infrared spectra of two enamino-ketones containing the trifluoromethyl group, namely, 4-(N-methylamino)- 1 and 4-(N,N-dimethylamino)-1, 1, 1 -trifluorobut-3-en-2-one 2 have been investigated in a number of solvents. It has been shown the title compounds possess spectral characteristics different from those of nonfluorinated analogues. Spatial and electronic structure features of these enamino-ketones are discussed.Keywords
