Sumario:Herein, the synthesis and characterization of the carbene‐stabilized boryl phosphinidenes 1–3 are reported. Compounds 1–3 are obtained by reacting Me‐cAAC=PK (Me(2)‐cAAC=dimethyl cyclic(alkyl)(amino)carbene) and dihaloaryl borane in toluene. All three compounds were characterized by X‐ray crystallography. Quantum mechanical studies indicated that these compounds have two lone pairs on the P center viz., an σ‐type lone pair and a “hidden” π‐type lone pair. Hence, these compounds can act as double Lewis bases, and the basicity of the π‐type lone pair is higher than the σ‐type lone pair.
