| Abstract: | A series of new 3-(3,4,5-trimethoxylphenyl)-4-aroyl-1 , 2, 't-triazoline-5-thione were prepared by the cyclization of 1- (3, -4, 5-trimethoxylbenzoyI)-'1-aroylthio-semicarbazides ! under the catalysis of 2 mol/L NaOH solution. The structures of the compound II series prepared were confirmed by the elemental analysis, IR and H-NMR. The regioselectivjty of the cyclization of the compounds I was rationalized with the fragments of mass spectra of the compounds II . |
