Taking 2，4，6-trinitrochorobenzene，2，4，6-trichoro-1，3，5-triazine and 4-amino-3，5-dinitropyrazole(LLM-116) as primary substances，1-(2，4，6-trinitrobenzene-1-yl)-4-amino-3，5-dinitro-pyrazole(Ⅰ) and 2，4，6-tri(4-amino-3，5-dinitropyrazole-1-yl)-1，3，5-triazine(Ⅱ) which have not been reported in the literature were synthesized by condensation reaction. Their structures were confirmed by IR，NMR and element analysis，and their melting point are 234-236 ℃，296.5 ℃(dec.)，respectively. The condensation reaction mechanism was discussed，and the optimal reaction conditions synthesizing 2，4，6-trichoro-1，3，5-triazine are as follows: reaction medium is N-methyl-2-pyrrolidone(NMP)，temperature is 70 ℃ and time is 16 h.
