Abstract
The present invention relates to a process for the preparation of N-substituted 2,6-dialkylmorpholines of the formula I in which Rand R, independently of one another, are hydrogen, alkyl or cycloalkyl, or Rand Rtogether with the carbon atom to which they are bonded are a 5- to 14-membered carbocycle, and Rand R, independently of one another, are alkyl or cycloalkyl, by reacting at least one carbonyl compound of the formula II in which Rand Rhave the meanings given above, with at least one morpholine of the formula III in which Rand Rhave the meanings given above, in the presence of hydrogen and at least one metal-containing catalyst, wherein the active component of the catalyst consists essentially of platinum group metals.
