Аннотация:Metallocenyl carbinols FcCH(2)OH (1a) and RcCH(2)OH (1b) dissolved in sc-CO2 penetrate into the acidic Nafion film under 20 MPa and 80 or 35 degrees C. After removal of pressure and leaving at room temperature, the crystals rapidly formed on the surface of the film, were identified as ethers McCH(2)OCH(2)Mc, Mc = Fc or Rc, by X-ray study. Mechanism of their formation is discussed. (C) 2009 Elsevier B.V. All rights reserved.
