%0 Journal Article %T Theoretical approach of the catalytic hydrochlorination of the 3-amino-2H-1,2,4-triazole %A Jean Baptiste Mensah %A Gaston A. Kpotin %A Georges Accrombessi %J Bulletin of the Chemical Society of Ethiopia %D 2009 %I Chemical Society of Ethiopia %X This study was aimed to determine the sites of protonation of the molecule during the hydrochlorination of 3-amino-2H-1,2,4-triazole. The catalytic reaction was carried out on the site MoS3H3+ and on the site ZnCl2. On both catalysts, the reaction led to a selective protonation of the molecule on the same atom of nitrogen of the cycle. But the reaction is endothermic and exothermic on the MoS3H3+ and ZnCl2 catalytic sites, respectively. The calculation method used is Hartree-Fock (HF) in the lanl2dz basis set. %K Catalytic hydrochlorination %K 3-Amino-2H-1 %K 2 %K 4-triazole %K Protonation %K MoS3H3+ %K ZnCl2 %K Endothermic %K Exothermic %U http://www.ajol.info/index.php/bcse/article/view/44967
