Monocyclic 1, 2, 3-triazines reacted with electron rich dienophiles to give pyridines and pyridazines. 4, 6-Disubstituted 1, 2, 3-triazine was denitrogenated to the azete intermediate, which afforded isomeric pyridines. 2, 5-Dihydrotriazines were oxidized by m-chloroperbenzoic acid to give 1, 2, 3-triazoles. Ring transformations of other triazine derivatives are also reported.
