Synthesis, Charactrization and Evaluation Biological Activity of some New Formazan Compounds Derived from Schiff Bases and Azo Compounds

摘要

The titled compounds (( twenty compounds )) were synthesized from series reactions of two types compounds ( azo and imine ) - compounds ., we prepared ten compounds from Schiff bases which react after that with diazo compounds to produce formazane compounds .All the synthesized compounds have been investigated using different chemical techniques, such as ( 1 H.NMR–spectra, , (C.H.N)-analysis, FT.IR–spectra ) some of them in 13 C.NMR–spectra , melting points and biological study
