<p>PROCESS FOR THE PREPARATION OF UNSATURATED COMPOUNDS The dimerization of acrylate esters and of ethene and the codimerization of acrylate esters with C2-4-alkenes or 1,3butadiene and of 1,3-butadiene with ethene in the presence of: (a) a Pd and/or Ru compound, (b) a compound containing one trivalent N or P atom, and (c) an Ag and/or Cu salt, yields at an increased reaction rate dimers of high linearity, when a quinone is also present.</p> |
