The impact of the strongly electron donating carbodiphosphorane moiety in the series of tri(phosphonio)methanide dications as triflate salts [(PhP)CP(X)Ph][OTf] (X = H, Me, CN, NCS, OH, Cl, OTf, F) deriving from [(PhP)CPPh][OTf] (19[OTf]) is presented. The influence of the introduced substituents X on the electronic structures of these dications is investigated by means of detailed NBO analysis, NMR spectroscopy and X-ray analysis.
本文介绍了源自[(PhP)CPPh][OTf]（19[OTf]）的三（膦鎓）甲烷二价阳离子系列三氟甲磺酸盐[(PhP)CP(X)Ph][OTf]（X = H、Me、CN、NCS、OH、Cl、OTf、F）中强供电子碳二磷烯部分的影响。通过详细的自然键轨道（NBO）分析、核磁共振光谱和X射线分析，研究了引入的取代基X对这些二价阳离子电子结构的影响。
