n, n΄-3, 4-di(methylamino)-1, 2, 5-oxadiazole (1f) was prepared by dehydration of n, n΄-3, 4-di(methylamino)glyoxime (2f) in aqueous potassium hydroxid at 170-180 ˚c. under similar conditions n, n΄-3, 4-di(benzylamino)-1, 2, 5-oxadiazole (1c) and n, n΄-3, 4-di(isopropylamino)-1, 2, 5-oxadiazole (1e) were not obtained, but, n, n΄-3, 4-di(ethylamino)-1, 2, 5-oxadiazole (1g) was appeared with smal...

This study aims to tested the antibacterial and antioxidant activities of two different plant extracts which were Syzygium aromaticum Capparis spinosa, five novel derivatives, i.e. [4-Nitro-N-((4-(N-(pyrimidin-2-yl) sulfamoyl) phenyl) carbamoselenoyl) Benz amide (1), 4-Methyl-N-((4-(N-(pyrimidin-2-yl) (2), sulfamoyl carbamothioyl) (3), 4-Nitro-N-((4-nitrophenyl) carbamo selenoyl) (4), N-(2,6-di...

Abstract Resolving the regioselectivity of N-position on nitrogen-rich heterocycles is an important task in synthesis high energy density materials (HEDMs). In this work we developed a simple two-step route to introduce 1,2,4-triazole into 4-nitro-1,2,3-triazole N2-position, which shows excellent regioselectivity. The target compound 4-nitro-2-(1 H -1,2,4-triazol-3-yl)-1,2,3-triazole (3) was ch...

The inhibiting effects of some newly synthesized Schiff bases on the corrosion of Al-Pure in 1.0 M HCl have been studied by means of the chemical and electrochemical methods. The Schiff bases m-Chloroaniline-N-benzylidene (m-CANB), p-Chloroaniline–N-benzylidene (p-CANB), Benzylamine-N-(p-methoxy benzylidene) (BANPMB) and 2-Phenylethylamine-N-(p-methoxy benzylidene) (2PANPMB) were synthesized fr...
