The stability of 1,2,3-triazoline adducts was studied and the structure of the products of their molecular rearrangements was established. The cycloadduct of azide with cyclohexanone enamine undergoes azapinacolone rearrangement involving a contruction of the cycloalkane ring by one member affording amidine of cyclopentanecarboxylic acid. The triazoline adduct of the azide with dicyclopentadiene as a result of the rearrangement affords the corresponding aziridinoquinoxaline. \\\\Expert2\\nbo\\Russian Journal of Organic Chemistry\\2005, 41 (11), 1694.pdf |

The values of the basicity constants characterizing the first protonation of the heterocycles investigated was in the range of acidity of the medium of pH 3.5 to H0 -2, and the second from H0 -7.3 to H0 -8.7. The position of the phenyl substituent proved to have a significant effect on the size of pK BH+. According to the results of ab initio calculations using HF/6-31G** for the heterocycles investigated the 1H+ form is thermodynamically most stable among the monocations, with the exception of 6-phenyl-1,2,4-triazine for which the existence of the monocation in the 1H+ and 2H+ forms are equally probable. In the case of the dications of all the triazines the 2,4-H,H2+ tautomer is the most preferred. The aromaticity of the 1,2,4-triazine ring is changed insignificantly on mono- and diprotonation. \\\\Expert2\\nbo\\Chemistry of Heterocyclic Compounds\\2003, v.39, N 5, p.616. .pdf |
