Synthesis and thermal decomposition of haloalkoxy-sym-triazines. 8. Synthesis and thermal decomposition of 2-methoxy(methylthio)-4-(2-chloroethylthio)-6-dialkylamino-sym-triazines

New 2-chloroethylthio derivatives of sym-triazine were obtained by the reaction of mercapto-sym-triazines and dichloroethane. It was established that these chlorides undergo cyclization to give 2-dialkylamino-4-oxo(thioxo)-4,5,6,7-tetrahydrothiazolo 1,2-a]-sym-triazines, the structure of which was confirmed by PMR and mass-spectral data, at moderate temperatures.See 7] for Communication 7.Translated f rom Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1275–1278, September, 1981.
