The ultrasound-promoted cyclocondensation of N1-amino-N 2-arylmethyl-(or aryl-) guanidines 2 with ethyl 2-amino-2- thioxoacetate furnished novel 3,6-diamino-substituted 1,2,4-triazin-5(2H)- ones 4 in moderate to high yields. The acyl

By known manners synthesized 1-amino-3-aryl-guanidines are oxidatively cyclized to corresponding 3,6-diarylamino-1,2,4,5-tetrazines in perchloric acid solution.The kinetics of this passing with second order model reaction was studied on a selected series of 17 1-amino-3-aryl-guanidine hydronitrates at 4 temperatures in 4 differently concentrated perchloric acid solutions of constant ionic strength by photometric concentration determination of oxidant cerium(IV).From experimental data rate constants, activation parameters and catalytic constants are evaluated by conventional methods, tabulated and discussed with regard to their substituent dependence.
