Summary The preparation and some properties of esters and amides of 3, 3- dialkyltriazenecarboxylic acids (6) are described. These novel triazenes 6 were obtained by treatment of diesters, diamides and ester-amides of 3, 3-dialkyltriazane-l, 2-dicarboxylic acids (3) with lead tetraacetate, when an elimination of the COOR-or the CONHR-group at N (2) together with the H-atom at N (l) took place. The precursor triazanes 3 were readily ...
