mono-aroylhydrazones of benzil are cyclised by ammoniumacetate in hot aceticacid to tri-substituted-1:2:4-triazines. The yield is favourable and it is not necessary, or even advantageous, to isolate the presumed intermediates. The new synthesis has been applied to a sufficient range of examples to establish its status as a general method. In the case of phenanthraquinone the reaction took a more complex course and

Diels–Alder (iEDDA)-type reaction to synthesize 1,3,5-trizines from acetophenones and amidines. The use of molecular iodine in a catalytic amount facilitates the functionalization of the sp3 C–H bond of acetophenones. This is a simple and efficient methodology for the synthesis of 1,3,5-triazines in good to excellent yields under transition-metal-free and peroxide-free conditions. The reaction is believed to

A series of 1,3,5-triazines were synthesized and their UV absorption properties were tested. The computational chemistry methods were used to construct quantitative structure-property relationship (QSPR), which was used to computer aided design of new 1,3,5-triazines ultraviolet rays absorber compounds. The experimental UV absorption data are in good agreement with those predicted data using the Time-dependent
