  A Phosphanyl‐Substituted Benzo‐1,3,2‐Dioxaborol as Ambiphilic Bifunctional Lewis Donor–Acceptor Unit

  摘要：

  AbstractCondensation of 3‐[(diphenylphosphanyl)methyl]benzene‐1,2‐diol (1) with phenyl boronic acid gave a phosphane‐functionalised benzo‐1,3,2‐dioxaborol 3. The ability of this species to act as a Lewis base through the P‐centered donor and as a Lewis acid through the B‐centered acceptor sites was demonstrated by the reactions with (cod)PdCl2 and some nitrogen donors (4‐dimethylaminopyridine, diaza‐[2.2.2]‐bicyclooctane, pyridine). These reactions yielded either palladium–phosphane complexes or amine–borane adducts that were characterised by spectroscopic data and, in some cases, by single‐crystal X‐ray diffraction studies. Reactions of a Pd complex of the phosphane‐functionalised benzo‐1,3,2‐dioxaborol 3 with dabco, or of the dmap adduct of 3 with (cod)PdCl2, gave materials that were characterised by analytical data and solid‐state NMR spectroscopic data as triple Lewis acid/base complexes and that contain both P→Pd and B←N dative bonds. Even though these adducts were unstable in solution, the results of these experiments demonstrate the ability of 3 to act as a bifunctional donor/acceptor ligand, which is of potential use as a building block for main chain organometallic polymers or multimetallic complexes.(© Wiley‐VCH Verlag GmbH & Co.
