(3,3,5,5-Tetranitropiperidin-1-yl)acetic acid is a novel and economical precursor for 1,3,3,5,5-pentanitropiperidine. Treatment of 2,2-dinitropropane-1,3-diol with glycine in water at 65-70 ËC for five hours gave (3,3,5,5-tetranitropiperidin-1-yl)acetic acid in 52% isolated yield. Nitration of the latter in a mixture of 100% nitric acid and trifluoroacetic anhydride for 12 hours gave 1,3,3,5,5-pentanitropiperidine in essentially quantitative yield. (3,3,5,5-Tetranitropiperidin-1-yl)acetic acid and 1,3,3,5,5-pentanitropiperidine were fully characterized by means of IR and NMR (¹H, ¹³C, and ¹5N) spectroscopy, differential scanning calorimetry, and elemental analysis.
(3,3,5,5-四硝基哌啶-1-基)乙酸是 1,3,3,5,5-五硝基哌啶的一种新颖而经济的前体。将 2,2-二硝基丙烷-1,3-二醇与甘氨酸在 65-70 ËC的水中处理 5 小时后,得到(3,3,5,5-四硝基哌啶-1-基)乙酸,分离收率为 52%。后者在 100%硝酸和三氟乙酸酐的混合物中硝化 12 小时后,得到 1,3,3,5,5-戊硝基哌啶,基本定量。(3,3,5,5-Tetranitropiperidin-1-yl)acetic acid 和 1,3,3,5,5-pentanitropiperidine 通过红外光谱、核磁共振(¹H、¹³C 和 ¹5N)光谱、差示扫描量热法和元素分析进行了全面表征。
