تحضير وتشخيص بعض المركبات الحلقية الخماسية الغير متجانسة من مشتقات البنزيدين /Preparation and Diagnosis of some non-Homogeneous Pentagram Derivatives of Benzidine

Abstract

This work comprise synthesis five membered  heterocyclic compounds type (1,2-azole) form benzidine derivatives, this work is distributed in to three  part :-

1- The one part of this study comprise preparation Diazoinum salt by reaction benzidine with NaNO₂ in acidic medium to produce A1 compound.

2-The two part of this study comprise preparation new azo compounds for benzidine by give  Diazoinum salt which buries by combination reaction with ethyl aceto acetate and acetyl acetone to produce A2 compound.

3-The three part comprise preparation new derivatives of pyrazoline-5-one, pyrazole, isoxazoline -5-one by reaction of compounds in one part with phenyl hydrazine,hydrazine hydrate to produce A3,A4,A5,A6,A7 compounds.

This compounds  may be have biological activity  in addition this can be used for  application in  oil, fuels and drugs . this  compounds was  studied and characterized by H¹ NMR , IR and C.H.N spectrum , the yield, percentage and boiling point was calculated
