摘要
Thermodynamic parameters of electrophilic substitution reactions of 1H-tetrazole and 1H-1,2,4-triazole proceeding by the addition-elimination and elimination-addition mechanisms were calculated by the DFT/B3LYP/6-31G(2df,p) method using proton as model electrophile and compared. The results obtained substantiate that the elimination-addition mechanism may not involve preliminary formation of N-protonated azolium salts, as was shown earlier in our DFT/B3LYP/6-31G(d,p) calculations.
