a class of 5-membered heterocyclic compounds containing a ring with two nitrogen atoms and three boron atoms. The 1,3,2,4,5-diazatriborolidine derivatives were synthesized from 1,2-bis(N-lithium-arylamino)diborane(4) and dichloro-dimethylaminoborane with high yield. The structures of these new derivatives were determined using nuclear magnetic resonance (NMR) spectroscopy. The molecular structures
摘要二氮杂硼硼烷衍生物是一类五元杂环化合物,具有两个氮原子和三个硼原子的环。由1,2-双(N-锂-芳基氨基)二硼烷(4)和二氯-二甲基氨基硼烷合成1,3,2,4,5-二氮杂三硼烷衍生物。这些新衍生物的结构是使用核磁共振(NMR)光谱确定的。使用单晶X射线衍射确定3a,3b,3d,4b和4c的分子结构。讨论了它们的结构特征,并与类似的二氮杂三硼烷类进行了比较。此外,理论上首次计算了包含五个成员杂环的B和N原子的形成焓。另外,据报道,一种简便有效的合成路线可用于制备1,3,2,4,
