Syntheses of some new formazan derivatives , derived frome isoniazid and study their biological activity

Abstract EN

This research includes the preparation of a new series of formazan derivatives .

In the beginning was prepared hydrazon derivatives through condensation izonzaid with compensators benzaldehyd different , then formazan derivatives were prepared by condensation hydrazon and diazonium salt different compensation for aromatic amines.

All the reaction completion were routinely monitored by TLC.The structures of the compounds have been confirmed by ,(C.H.N) analysis of the elements for some compounds , 1H NMR, IR spectral data and melting points.

The antibacterial activity of the compounds has also been screened.
