The Klopman-Peradejordi-Gómez method relates the variation of a biological activity, measured in vivo or in vitro, with the variation of the numerical values of a set of local atomic reactivity indices (LARIs). The introduction of local atomic reacti [...]
The theoretical study of alkylation of 4-amino-1,2,4-triazol (C2N4H4) in the presence of aluminum chloride (AlCl3) was carried out by quantum chemical methods HF and DFT, in Lanl2Dz basis set. The results show that N-alkyl product is favorable ther [...]
