The isomers, 1,3,3-trimethyl-5-nitro-3-(4-nitrophenyl)-2,3-dihydro-1H-indene (1) and 1,3,3-trimethyl-5-nitro-1-(4-nitrophenyl)-2,3-dihydro-1H-indene (2), have been prepared and separated effectively. Their crystal structures can not be confirmed by the results of IR, 1H NMR, 13C NMR and MS studies, but determined by X-ray diffraction. The structure identity has explained the precise configurations of title compounds. DSC/TG analysis illustrate that the isomers 1 and 2 possess excellent thermal stability.
1,3,3- 三甲基-5-硝基-3-(4-硝基苯基)-2,3-二氢-1H-茚(1)和 1,3,3- 三甲基-5-硝基-1-(4-硝基苯基)-2,3-二氢-1H-茚(2)这两种异构体已被制备出来并得到有效分离。它们的晶体结构无法通过红外光谱、1H NMR、13C NMR 和 MS 的研究结果来确认,但通过 X 射线衍射可以确定。结构鉴定解释了标题化合物的精确构型。DSC/TG 分析表明,异构体 1 和 2 具有出色的热稳定性。
