1, 2, 4 - triazole-aldehydes

2023
Althouth many C-aldehydes of azoles and azines, including those of 1,2,3-triazoles, are known and readily obtainable, free aldehydes derived from 1,2,4-triazole do not appear to have been isolated previously. The main aim of the work submitted in this thesis was the synthesis of such 1,2,4-triazole-C-aldehydes.

Reaction of 3-amino-1:2:4-triazole with lactoperoxidase

Archives of Biochemistry and Biophysics, 1973
Bovine lactoperoxidase (LPO) gradually lost its enzymatic activity when dialyzed against a solution of 3-amino-1:2:4-triazole (AT) and hydrogen peroxide at pH 7.0. Amino acid analysis of the completely inactive enzyme revealed the formation of a new ninhydrin-positive chromatographic peak.

Synthesis of some nitro and amino derivatives of 1, 2, 4-triazole-5-thiones and 1, 2, 4-triazoles

Chemistry of Heterocyclic Compounds, 1967
Isomeric 3-(nitrophenyl)-1, 2, 4-triazole-5-thiones are synthesized by cyclizing 1-nitrobenzoylthiosemicarbazides. 1-(4-Nitrophenyl)-1, 2, 4-triazole-3-thione is prepared by condensing 4-(4-nitrophenyl) thiosemicarbazide with formic acid. Oxidation converts the triazolethiones to nitrophenyltriazoles, and the latter are reduced to aminophenyltriazoles.

Synthesis of 5-amino-1-(aminothioformyl)-1, 2, 4-triazoles

Chemistry of Heterocyclic Compounds, 1971
By the reaction of 5-amino-1, 2, 4-triazoles with benzoyl isothiocyanate we have synthesized 5-amino-1-(benzoylaminothioformyl)-1, 2, 4-triazoles, which form 5-amino-1-(aminothioformyl)-1, 2, 4-triazoles on alkaline hydrolysis.

1 : 2 : 4-triazole as a corrosion inhibitor for copper

Corrosion Science, 1980
Abstract The solution chemistry of 1 : 2 : 4-triazole (TRZ) is investigated in the range of solution concentrations in which the compound acts as a corrosion inhibitor for copper. Parallel photo-electron spectroscopic studies show that although a surface layer of Cu(I) complex is formed at low TRZ concentrations, this is ineffective as an inhibitor ...

Basicity and structure of 1, 2, 4-triazole derivatives

Chemistry of Heterocyclic Compounds, 1967
Basicity constants for a number of 1, 2, 4-triazole derivatives are determined. An assumed amine structure for 3-amino-1, 2, 4-triazoles in aqueous solution is demonstrated. It is assumed that protonization of 3- and 4-amino-1, 2, 4-triazoles occurs at the nitrogen in the heterocyclic ring, and not at the amino group.

The preparation of 3:5‐dimethyl‐1‐phenyl‐1:2:4‐triazole

Journal of Applied Chemistry, 1952
AbstractOptimum conditions for the laboratory‐scale preparation of 3 : 5‐dimethyl‐1‐phenyl‐1 : 2 : 4‐triazole by the Einhorn‐Brunner method have been studied. The mechanism of the reaction is different from those involved in the triazole syntheses of Pellizzari and Kaiser.
