Abstract
2-(2,4,6-Trioxo-[1,3,5]triazinan-1-yl)ethyammonium halides 3–5 were prepared starting from 2-(methylthio)-7,8-dihydroimidazo[1,2-a]-1,3,5-triazin-4(6H)-thione (1). First, compound 1 was S4-methylated to give 2,4-bis(methylthio)-6,7-dihydroimidazo[1,2-a][1,3,5]-triazine (2) which, in turn, was hydrolyzed with corresponding aqueous solution of hydrogen halide. X-ray crystallographic study revealed that in crystals of 2-(2,4,6-trioxo-[1,3,5]triazinan-1-yl)ethylammonium iodide (5) a chain of alternatively arranged anions and cations extending along [001] is formed through polymeric (anion-π)n interactions.
摘要
从2-(甲硫基)-7,8-二氢咪唑[1,2-a]-1,3,5-三嗪-4(6H)-硫酮 (1) 开始制备了2-(2,4,6-三氧代-[1,3,5]三嗪-1-基)乙基铵卤化物 3–5。首先,化合物 1 被S4-甲基化以得到2,4-双(甲硫基)-6,7-二氢咪唑[1,2-a][1,3,5]-三嗪 (2),然后,化合物2被相应的氢卤酸水溶液水解。X射线晶体学研究揭示,在2-(2,4,6-三氧代-[1,3,5]三嗪-1-基)乙基铵碘化物 (5) 的晶体中,通过聚合物 (阴离子-π)n 相互作用形成了沿 [001] 方向交替排列的阳离子和阴离子链。
