Investigations of the synthesis and chemical properties of nitro-and polynitromethyl derivatives of 1,3,5-triazine have been actively carried out in recent years [1][2][3][4][5][6][7][8][9]. Our work is also based on a study of the reactivity of trinitromethyl derivatives of 1,3,5-triazine and concerns the potential synthesis of previously unreported polynitromethyltetrazolo-1,3,5-triazines in which a tetrazole ring is annelated to the 1,3,5-triazine ring.The general method for preparing condensed tetrazoles is based on the annelation of tetrazole to the triazine ring via an azido-tetrazole tautomeric conversion of the azidoazomethine fragment in the molecule [10,11]. For azido-1,3,5-triazines which contain electron-donor substitutents this question has been considered in [12,13].NaN 3 3a, 4a R 1 = R 2 = Me; 3b, 4b R 1 = R 2 = Et __________________________________________________________________________________________
