摘要

在Mn(I)配合物[Cp(CO)2Mn(IMes)]中，a -(CH2)2PR3+部分接枝在NHC配体主链上，然后进行双去质子化，开辟了一条获得具有极端供电子特性的双齿配体的途径。这种显著的电子性质甚至可以在典型的惰性方形平面Rh(I)二羰基配合物中允许分子内sp2 C-H功能化。

Pushing the limits of electron donation for cis-chelating ligands via an alliance of phosphonium ylide and anionic abnormal NHC.

The grafting of a -(CH₂)₂PR₃⁺ moiety on an NHC ligand backbone in the Mn(I) complex [Cp(CO)₂Mn(IMes)] followed by double deprotonation opens a route to bidentate ligands with extreme electron-donating character. Such remarkable electronic properties can even allow intramolecular sp² C-H functionalization in typically inert square-planar Rh(I) dicarbonyl complexes.
