Calculation of the dipole moments and heats of formation for 1,2,4-triazole confirmed that it exists primarily in the unsymmetrical form, while similar calculations for 3-amino- and 3,5-diamino-1,2,4-triazoles showed that the amino tautomers with a h

3-Chloro- and 3-amino-1,2,4-triazole derivatives were subjected to a theoretical study by means of quantum-chemical calculation by the Pariser-Parr-Pople method. The experimentally observed electron transitions were assigned. The Cl atom and the NH2

The conditions were found for the hydrosilylation of CH2=CHSi(OC2H5)3 with triorganylsilanes in the presence of H2PtCl6 · 6H2O in isopropanol, which assured a high yield (>90%) of the 1-(triorganylsilyl)-2-(tri-ethoxysilyl)ethanes. These conditions

5-Substituted 3-chloro-1,2,4-triazoles were synthesized by diazotization of 5-substituted 3-amino-1,2,4-triazoles in hydrochloric acid. In addition to replacement of the amino group by a chloro group, diazotization of 5-aryl-3-aminotriazoles at high

The manifestation of acid-base interactions in the electronic absorption spectra of 32 1,2,4-triazole derivatives was studied. Ionization of the heteroring does not have a substantial effect on the energies of the electron transitions of 3-chloro-5-s
