Conclusions
-
1.
The behavior of diazonium salts in solutions was studied by means of the IR absorption spectra in the region of 2200–2300 cm−1. Diazonium salts are dissociated into ions in dimethylformamide, methanol, acetone, and ethyl acetate.
-
2.
In dilute solutions the frequency of the valence vibrations of the triple bond does not depend on the character of the anion. When the concentration is increased (40–60%), it varies according to the nature of the anion.
-
3.
The frequency of the valence vibrations of the triple bond of the diazo cation depends little on the polarity of the solvent. The addition of certain inorganic salts to the solutions somewhat reduces this frequency; of the salts studied, FeCl3 and SbCl3 cause the greatest reduction.
