iajs-1866	Hussain, Eman M.; Naji, Hussam Z.	Synthesis , Characterization and Study of Biological Activity of Some New Schiff Bases ,1,3-Oxazepine and Tetrazole Derived from 2,2 di thiophenyl Acetic Acid	2018	14	.pdf	application/pdf	3160	179	68	Compounds 2-3 were synthesized from the reaction of compound 1 with methanol or ethanol respectively in the presence of Sulfuric acid as catalyst. Compounds 5-8 were synthesized from the reaction of compound 4 with different aromatic aldehyde and ketone by using glacial acetic acid as catalyst, the FTIR spectra of these compounds showed the disappearance of two absorption bands (3423) cm-1 and (3309) cm-1 of the (NHNH2) group and appearance of new band at range between (3188 - 3115 ) due to NH group .	cache/iajs-1866.pdf	txt/iajs-1866.txt
