- Polynuclear nonfused bis(1,3,4-oxadiazole)-containing systems
-
Nonfused bis-1,3,4-oxadiazoles were synthesized by reaction of 5-substituted mono- and bis-tetrazoles with mono- and dicarboxylic acid chlorides. The results of kinetic studies showed that the transformation of tetrazoles into 1,3,4-oxadiazoles is accelerated by 1 to 2 orders of magnitude on addition of a catalytic amount of dimethylformamide, triethylamine, or pyridine.
