Titel compounds can be obtained either by condensation of chinolinaldehyds with aminoguanidins in a ethanol/water mixture in the presens of Protones (way A), or starting with chinaldines via aniles or nitrones and reaction with aminoguanidinsalts (way B).Way B has any advantages and is described by examples.

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.
