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-aldehydes

1962
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.

Die Röntgenstrukturanalyse von 1, 2, 4‐Triazol

Berichte der Bunsengesellschaft für physikalische Chemie, 1965
AbstractDie Kristallstruktur von 1, 2, 4‐Triazol, C2N3H3, wurde durch dreidimensionale Analyse der Röntgenbeugungsdaten ermittelt. Die Kristalle sind rhombisch (Raumgruppe Pbca‐D152h) mit 8 Molekülen in der Elementarzelle. Die Gitterkonstanten haben die Werte: a = 9,69 ± 0,04 Å, b = 9,38 ± 0,04 Å, c = 7,14 ± 0,03 Å.

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.

QSAR Study of 1, 2, 4-Triazole for their Anticancer Activity

Asian Journal of Research in Chemistry
Considerable attention has been given to searching for novel anticancer drugs concerning the disease sequelae on human health and well-being. The objective of the present study was to carry out the QSAR evaluation on the substituted 1, 2, and 4-triazole derivatives for anticancer potential using the k-Nearest Neighbor Molecular Field Analysis (kNN-MFA)

ChemInform Abstract: 1:2:4‐TRIAZOLE AS A CORROSION INHIBITOR FOR COPPER

Chemischer Informationsdienst, 1980
AbstractBei niedrigen Konzentrationen wirkt 1,2,4‐Triazol (I) in wäßrigen NH4Cl‐Lösungen nicht als Korrosionsinhibitor für Cu, obwohl sich an der Cu‐Oberfläche ein Cu(I)‐Komplex bildet.
