摘要：
Four Schiff bases, derived from 2-thenoyltrifluoroacetone with methyl amine, ethyl amine, propyl amine and phenyl amine and their thione derivatives have been synthesized. The compounds were characterized by melting point, IR, NMR and microanalysis. Analysis of the IR and NMR spectra indicates that the condensation occurs at the carbonyl group adjacent to the CF3 moiety. Furthermore, the product exists mainly in the keto amine form. Subsequent-thiolation of each Schiff bases occurs at the carbonyl adjacent to the thiophene ring and the product has the thione amine. The present study has shown that the structures of the synthesized compounds are as follows: [GRAPHICS] .
