Ultraviolet absorption data suggested the presence of a pyridinium cation for pyridotriazole in acid solutions. Dilute acid and neutral solutions of 1-phenylpyridotriazole showed identical ultraviolet absorption patterns. At higher temperatures, pyridotriazole in carboxylic acids or phenol released nitrogen with the formation of corresponding esters of 2- pyridylmethanol or phenyl 2-pyridylmethyl ether, respectively. The less basic 1- ...
