1,2-Bis(diphenylphosphino)benzene and two related mono-methiodides, [o-C₆H₄(PR₂)(PR₂Me)]I (R = Ph or Me)

W. Levason, G. Reid and M. Webster

Abstract: The structures of the compounds 1,2-bis(diphenylphosphino)benzene, C₃₀H₂₄P₂, [2-(diphenylphosphino)phenyl]methyldiphenylphosphonium iodide, C₃₁H₂₇P₂⁺·I^-, and [2-(dimethylphosphino)phenyl]trimethylphosphonium iodide, C₁₁H₁₉P₂⁺·I^-, show that quaternization only occurs at one P centre and results in significantly shorter P-C bonds and larger C-P-C angles, consistent with the formal oxidation from P^III to P^V.

Formula: C₃₀H₂₄P₂, C₃₁H₂₇P₂⁺·I^- and C₁₁H₁₉P₂⁺·I^-
