The ongoing study is a Ugi-azide four-component reaction for the synthesis of 1,5-disubstituted tetrazole(1,5-DST), which involves an aldehyde, different amines, isocyanides, and as azide’s source Trimethylsilylazide (TMSN3), in water solvent using catalyst tetradecyltrimethylammonium bromide (TTAB) with load (10% mole), provides hydrophobic micellar site. This approach step toward green chemis...

the synthesis of 3-amino-1-nitroguanidine (3-anq) and 5-hydrazino tetrazole (5-ht) derivatives as new energetic materials are described. reaction of 3-anq with triethyl orthoformate leads to the formation of 3-nitramino triazole while no reaction was observed whit 5-ht. addition of nan3 to a mixture of 3-anq and triethyl orthoformate, afforded 1-nitroguanidyl tetrazole in excellent yield. on th...

This work involved the synthesis of tetrazole derivatives 4,4'-(((sulfonylbis(4,1-phenylene))bis(diazene-2,1-dil))bis(2-(1-(4-R)phenyl]-4),5-Dihydro-1H-tetrazol-5-yl(phenol) (where R = OH or OCH3) through reaction substituted amine in THF as a solvent, with sodium azide. FT-IR 1H-NMR Spectrophotometric methods were used to characterize prepared compounds, antibacterial activity against four typ...

Purpose: The article is aimed to synthesize,characterize and screening the biological activity of a series of Synthesis of 1-(2-(3-(3-chloro-1-(4-substituted phenyl)-4-tetrazole-2-yl)-1H-indol-1-yl)acetyl)-4-(2-(4substituted phenyl)hydrazono)-3-(trifluoromethyl)-1H-pyrazol-5(4H)-one 4(a-f). Indole-3-carbaldehyde and chloro ethyl acetate were dissolved in DMF. To this reaction mixture anhydrous ...

Abstract In order to apply the high nitrogen-content tetrazole derivatives (TZD), a class of energy materials with great potential, into gun propellant, we propose novel idea that grafting acidized TZD onto cellulose and then nitrifying grafted obtain nitrocellulose by (TZDNC). Theoretical predictions suggest Replacing (NC) TZDNC, due having higher TZDNC than traditional NC, can evidently reduc...

The title compound, C(7)H(13)N(5), a tetrazole analogue of betaines, exists as a zwitterion, with the H atom of the tetrazole ring being transferred to the piperidine ring N atom. The tetrazole ring symmetry is close to C(2v), which suggests strong charge delocalization in the N-C-N fragment of the ring. There are classical hydrogen bonds in the structure which are responsible for the formation...

The metal-organic framework [Cd15(5MT)18(OH)4(SO4)4] (5-MT = 5-methyl-1H-tetrazole) with an unprecedented Cd(3)(micro3-OH)(micro3-SO4) core and two kinds of tetrazole coordination modes was formed by self-assembly and in situ synthesis of the 5-MT tetrazole ligand; the structure exhibits an unusual 3(9) x 4(12) x 5(15) topological network and shows reversible shrinkage and expansion in a crysta...
