“…These frequencies shifted towards longer wavelengths after dissociation from the metal ion (14) indicating the occurrence of dissociation. Additionally, distinctive bands appeared at frequencies of (1201-1105 cm -1 ), attributed to both symmetric and asymmetric (C-O-C) nitro group [24].…”

In this research, acetophenone and thiourea reacted in the presence of iodine to produce 2-amino-4-phenylthiazoles (1, 2). These compounds were then used in three different reactions to create substituted Schiff-bases (3-5) by further reactions with substituted benzaldehyde. To produce thiazole, they were first reacted with sodium azide (6). After adding maleic anhydride, they interacted with thioglycolic acid to yield oxazepine (7), and lastly, thiazolidine (8). The synthesised compounds (1-8) were confirmed to have their structures clarified by CHNS and spectroscopic methods such as infrared, 1H NMR and 13C NMR. After being produced (1-4, 6-8), these compounds were used in 2:1 ratio reaction with CoCl2.6H2O to generate cobalt complexes (9-15). These complexes' magnetic characteristics, thermal analysis (TGA), and differential thermal analysis (DTA) were investigated. Several produced compounds were also tested against the growth of four different types of bacteria. KEY WORDS: Schiff-bases, Thiazole, Oxazepine, Thiazolidine, Cobalt complexes Bull. Chem. Soc.

Azo-aldehyde derivative (2) was prepared through reaction of 2-hydroxybenzaldehyde with diazonium ion generated from 2-aminobenzothiazole (1). The producing aldehyde (2) was then treated with some anilines consisting (4-nitroaniline, 3-nitroaniline, 4-aminophenol, 4-methoxyaniline, 4-bromoaniline, 4-chloroaniline and 2,4-dichloroaniline) by (MW) method to give seven Schiff bases (3a-g). Cyloaddition reactions of Schiff bases (3a-g) and phthalic anhydride utilizing (MW) means in dry benzene yielded seven new 1,3-benzoxazepine-1,5-diones (4a-g) carrying the unit of benzothiazole. Determination of verves of final benoxazepines athwart bacteria done on Staphylococcus aurous (Gram-positive) and Escherichia coli (Gram-negative). The outputs showed that all benzoxazepine compounds exhibited greater activity to standard antibiotic (gentamycin) athwart Staphylococcus aurous. Moreover, the benzoxazepines (4a, 4b, 4c, 4d, 4e and 4g) appeared best activity athwart Escherichia coli comparably with that of standard antibiotic.
