X射线晶体学显示为平面RhP2C结构,课题组人员得到了一种基态构型为02的铑配位阳离子环二膦卡宾, Liu Leo Liu IssueVolume: 2024-01-05 Abstract: Isolable singlet carbenes have universally adopted a 20 electronic state,如何共同稳定了碳烯中心形式空的轨道和填满的轨道, cationic cyclic diphosphinocarbene with a 02 ground state configuration. Nuclear magnetic resonance spectroscopy studies show a carbene carbon chemical shift below 30.0 parts per million. X-ray crystallography reveals a planar RhP2C configuration. Quantum chemical calculations rationalize how -electron delocalization/donation and -electron negative hyperconjugation together stabilize the formally vacant orbital and the filled orbital at the carbene center. In contrast to traditional carbene counterparts this carbene can undergo synthetic transformations with both a Lewis base and a silver salt。
