Thermal Isomerization of O-Chlorophenyltetrazolocyclanopyrimidine with Different Structure Types

Temperature dependence of the 1H NMR spectra and TLC data suggest turning the corner isomers of о-сhlorоpheniltetrazolocyclanopyrimidine in the thermodynamically more stable linear forms. The IR spectra were recorded isomeric azide intermediate transformations.

Reaggregation Positional Isomers Tetrazologeksahidroquinazoline

9-phenyl-4,5,6,7,8,9-geksagidrotetrazolo[5,1-b]quinazoline in solution undergoes reaggregation ent via an azide to form a positional isomer corner structure that is installed involving spectral methods (1H-NMR, IR -spectra), TLC, chromato-mass spectrometry.
