Various of 2,5- disubstituted 1,3,4-oxadiazole (Schiff base, ?- lactam and azo) were synthesized from 2,5-di (4,4?-amino-1,3,4-oxadiazole which usequently synth-esized from mixture of 4- amino benzoic acid and hydrazine arch of polyphosphorus acid. The synthesized compounds were cherecterized by using some spectral data (UV, FT-IR , and 1H-NMR)

The aim of the present paper was the synthesis and chemical characterization of some original compounds with dibenzo[b,e]thiepine structure. The synthesis of the new compounds was performed in several stages. Thus, by reaction of phtalide with thiophenol potassium salt, we obtained the 2-phenylthiomethyl-benzoic acid. The acid was cyclized with polyphosphoric acid to the desired 6,11-dihydrodibenzo[b,e]thiepin-11(6H)-one, converted afterwards to the corresponding oxime and subsequently to the O-acyloximino-dibenzo[b,e]thiepins by acylation with various substituted benzoic acid chlorides. The oxidation of O-acyloximino-dibenzo[b,e]thiepins with hydrogen peroxide afforded the corresponding sulfones. The new compounds, four O-acyl-oximino-dibenzo[b,e]thiepins, and four O-acyl-oximino-dibenzo[b,e]thiepin-5,5-dioxides, have been characterized by their physical constants (melting point, solubility) and their structures and purity were confirmed by elemental analysis, and spectral analysis (IR, 1H-NMR, 13C-NMR).

An attempt to synthesize the benzoimidazol derivatives from the reaction of o-phenylenediamine and benzoic acid derivatives in the presence of ethanol and various ketones under microwave irradiation, 1 , 5 - benzodiazepinum salt derivatives were obtained instead of them. Unexpected reaction was happened for synthesis a new series of benzodiazepinium salt derivatives in a selective yield . The reaction mechanism was also discussed. The new compounds were purified and identified their structures were elucidated using various physical techniques like; FT- IR spectra, micro elemental analysis (C.H.N) and 1H NMR spectra.

New Compounds

It is well known that many compounds bearing thioureide structure have been reported to have antimicrobial activity and some of these thioureide compounds are found to be associated with other therapeutical activities. The present application is a continuation of our research concerning the synthesis and characterization of 2-(4-methyl-phenoxymethyl)benzoic acid thioureides with antimicrobial activities. The new thioureides were obtained in three stages. In the first stage we prepared the 2-(4-methyl-phenoxymethyl)benzoic acid by reacting potassium para-cresolate with phtalide. The second stage consists in the synthesis of the 2-(4-methyl-phenoxymethyl)benzoic acid chloride and, in the third phase, the acid chloride aforementioned is refluxed with ammonium thiocyanate the resulting 2-(4-methyl-phenoxymethyl)benzoyl isothiocyanate being treated with primary aromatic amines to obtain the new compunds. We established the optimal reaction conditions for the new compounds synthesizing process of with high purity and yields. The new compounds, which are not mentioned in the literature concerning this domain, have been characterized by their physical properties (melting point, solubility) and the structures were confirmed by elemental analysis, 1H-NMR, 13C-NMR and IR spectral methods.
