Synthesis and thermal decomposition of haloalkoxy-sym-triazines

The reaction of 4,6-bis[alkyl(dialkyl)amino]- or (4-alkylamino-6-dialkylamino-sym-triazin-2-yl)trimethylammonium chlorides with ethylene chlorohydrin and the action of phosphorus pentachloride on 2--hydroxyethoxy-sym-triazines give 2--chloroethoxy derivatives of sym-triazine, which on heating are converted to imidazo[1,2-a]-sym-triazine derivatives.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, pp. 262–265, February, 1977.
