AI Article Synopsis

  • The text discusses model compounds designed for silica surfaces that are modified using metal complexes, specifically mentioning certain anionic structures.
  • The two types of complexes highlighted are mononuclear anionic diperoxo species and dinuclear complex anions involving metals like molybdenum (Mo) and tungsten (W).
  • These complexes are synthesized in good to nearly quantitative yields through specific chemical reactions with phenyl silanol (Ph SiOH) and another silanol compound in the presence of an aqueous metal solution.

Article Abstract

Model compounds for silica surfaces modified with metal complexes are provided by the mononuclear anionic diperoxo species 1 and the dinuclear complex anions 2 (M = Mo, W). They were obtained in fair to nearly quantitative yields by the reactions of Ph SiOH and [Ph Si(OH)] O, respectively, with an aqueous solution of [MO(O ) (H O) ].
