Abstract
Reaction of aroylhydrazides with 2,4,6-trimethylbenzoyl chloride in the presence of Et3N afforded N-(mesityl)aroylhydrazides, which through subsequent cyclization at treatment with SOCl2 resulted in 2-aryl-5-(2,4,6-trimethylphenyl)-1Н-1,3,4-oxadiazoles. For 2-hydroxyphenyl derivative containing a stable O–H N intramolecular bond a low quantum luminescence yield is observed (φ 0.006–0.038) due to the nonradiative deactivation of the agitated state by ESPIT mechanism.
