Abstract

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.

Key words: 
tetrazoloquinazolines, positional isomers, azido-tetrazole reaggregation, 1H NMR, IR spectra, chromato-mass-spectrometry
