We report the synthesis of [H 2 B(pz) 2 PR] + , [H 2 C(pz) 2 PR] +2 , [HB(pz) 3 P] +2 , and [HC(pz) 3 P] +3 (H 2 B(pz) 2 =bis(pyrazolyl)borate; H 2 C(pz) 2 =bis(pyrazolyl)methane; HB(pz) 3 =tris(pyrazolyl)borate; HC(pz) 3 =tris(pyrazolyl) methane; R=Ph, Cy or Et 2 N) by reaction of the corresponding neutral or anionic ligands with chlorophosphines in the presence of TMSOTf. The structures of these compounds were determined by X‐ray crystallographic analysis and the nature of their bonding was examined using density functional theory.
