Conversion of Bestmann Ylide into Carbophosphinocarbene

Angewandte Chemie International Edition, EarlyView.
The ortho‐carboranyl carbophosphinocarbene(CPC) was synthesized via a click‐type reaction. Experimental and computational studies reveal its remarkable electron‐donating ability. Reactivity studies demonstrate its versatility as a stabilizing ligand, a strong nucleophile for CO₂ activation, and a potent Brønsted base for imidazolium deprotonation ...
