Complexes of a Frustrated Lewis Pair‐Supported P(−1) Ligand
Several complexes of the intramolecular frustrated Lewis pair (FLP)-supported P(-1) ligand [<sup>i</sup>Pr<sub>2</sub>P(C<sub>6</sub>H<sub>4</sub>)BCy<sub>2</sub>{P}]<sup>-</sup> are presented (Cy=cyclohexyl). Chief among these is the first example of a monomeric zinc bis(phosphido) complex, which was synthesized as a potential precursor for the solution-phase deposition of Zn<sub>3</sub>P<sub>2</sub>. While this goal was ultimately unsuccessful, the Zn(II) complex acts as a convenient springboard to other metal phosphide species via transmetallation: affording a tellurium bis(phosphido) complex and a formal adduct of the phosphorus subhalide PPCl<sub>2</sub>. Trapping experiments show that the PPCl<sub>2</sub> adduct can also be prepared directly through the in situ reduction of PCl<sub>3</sub> in the presence of an intramolecular FLP ligand. Lastly, we report a formal η<sup>2</sup>-phosphaborene complex of cobalt(-1) which is isoelectronic to olefin complexes, and explore its bonding via density functional theory (DFT) computations.
