Definitions

  • the proton donor used is primarily protic compounds which are liquid at room temperature, such as alcohols, primary or secondary amines or water, in particular branched or unbranched C1 to C5 alcohols, such as methanol, ethanol, propanol, isopropanol, tert-butanol or Pentyl alcohol.
  • protic compounds which are liquid at room temperature, such as alcohols, primary or secondary amines or water, in particular branched or unbranched C1 to C5 alcohols, such as methanol, ethanol, propanol, isopropanol, tert-butanol or Pentyl alcohol.
  • Good activation of the sodium succeeds above all with the alcohols mentioned, in particular methanol or ethanol, and water.
