N′′-Disulfonamide-1,3,5-triazinanes were synthesized and characterized by X-ray single crystal structure analysis. In the course of the X-ray structure elucidation, the first solid experimental evidence of the axial position of the tert-butyl group in unconstrained hexahydro-1,3,5-triazacyclohexanes was obtained. Dynamic low-temperature NMR analysis allowed to fully investigate a rare case of crystallization-driven
合成了Nt -Bu- N '、N ''- Disulfonamide -1,3,5-triazinanes,并通过X射线单晶结构分析对其进行了表征。在X射线结构解析过程中,首次获得了无约束六氢-1,3,5-三氮杂
环己烷中叔丁基轴向位置的可靠实验证据。动态低温核磁共振分析允许充分研究饱和六元循环的椅子构象中叔丁基的结晶驱动解锚的罕见情况。DFT 计算表明,必须使用显式溶剂分子来解释t的赤道位置-Bu 组在溶液中。否则,轴向构象异构体是热力学稳定的异构体。
