A series of new triazolopyridine-based phosphines has been prepared. These compounds revealed unexpected spectroscopic patterns. In particular, the NMR spectra are highly dependent on the relative conformational preference of the phosphine substituent at C7. Here, we report on their complete NMR analysis, X-ray structures and DFT calculations that confirm the particular arrangement of the phosphorus lone pair orbital related to the substituent pattern of the chosen phosphine.
一系列新的三唑并吡啶基膦已经被制备。这些化合物显示出了意想不到的光谱模式。特别是，NMR 谱高度依赖于 C7 位膦取代基的相对构象偏好。在这里，我们报告了它们的完整 NMR 分析、X 射线结构和 DFT 计算，这些计算证实了磷孤对轨道与所选膦取代基模式相关的特殊排列。
