Abstract

Synthesis of new Schiff bases and its thione derivatives from 2-thenoyltrifluoroacetone has been carried out . The metal complexes of these reagents were prepared. In addition new metal complexes of the 2-thenoyltrifluoroacetone reagent are also prepared. The prepared compounds have been characterized by melting points, CHN analysis, I.R, NMR and TGA techniques. A full analysis of CHN, I.R, NMR spectra and TGA carves of the studied compounds gave the molecular structures of the compounds., the study has involved preparations of two Schiff bases derived from 2-thenoyl-trifluoroacetone with methyl amine and ethyl amine and their thiones derivatives and proved their structures.
