Reagent for Introducing Base-Stabilized Phosphorus Atoms into Organic and Inorganic Compounds

The cyclic alkyl­(amino) carbene (cAAC) stabilized monoanionic phosphorus atom in the form of lithium phosphinidene [cAACPLi­(THF)₂]₂ (<b>1</b>) has been isolated as a molecular species and characterized by single crystal X-ray structure analysis. Furthermore, the structure and bonding of compound <b>1</b> has been investigated by theoretical methods. The utilization of the lithium phosphinidene as a phosphorus transfer reagent for a wide range of organic and inorganic substrates has been investigated. Herein, we report on the preparation of fascinating compounds containing P–C, P–Si, P–Ge, and P–P bonds using a single step with a base-stabilized phosphorus atom
