## Abstract The acid catalyzed condensation of 4,5βdiaminopyrazoles and chalcones gave the hitherto unknown 1βbenzylβ2,4,6βtriphenylβ2,3βdihydropyrazolo[3,4β__b__][1,4]diazepines derivatives. The structure of all products was supported by ir, ^1^H and ^13^Cβnmr and mass spectra.
The thermal decomposition reactions of dihydro-3,6-diphenyl-5-benzyl-1,2.4,5-trioxazine ( D H T ) in the initial concentrations and temperature ranges of 0.004-0.013 M and 353-393 K, respectively, have been investigated in benzene, toluene, and methanol solutions In these solvents the reaction follo
