Abstract

In the presence of conformational preference, the R(H)P–P(H)R diphosphanes show a unique correspondence between the isomeric/conformational structure and the ¹J_PP/³J_HH NMR spin-spin coupling constants (SSCCs). A joint analysis of SSCC values solves a problem with two unknowns: conformational and isomeric structures of such systems. The applicability of the approach to specific problems is demonstrated.

核磁共振在R(H) P-P (H)R二膦结构分析中的应用：可能性和局限性

在构象偏好存在的情况下，R(H) P-P (H)R二膦的异构体/构象结构与1JPP/3JHH核磁共振自旋-自旋耦合常数（SSCCs）具有独特的对应关系。SSCC值的联合分析解决了两个未知的问题：这类体系的构象结构和同分异构体结构。论证了该方法对具体问题的适用性。
