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 (1) has been isolated as a molecular species
and characterized by single crystal X-ray structure analysis. Furthermore,
the structure and bonding of compound 1 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.
