摘要： The invention relates to the preparation and use as catalysts of diphosphines of the formula (I) in which R is C6-C14-aryl or C4-C13-heteroaryl containing 1 to 3 heteroatoms selected from the group consisting of nitrogen, oxygen, and sulfur, wherein the aryl and heteroaryl radicals may optionally be substituted by halogen, C1-C6-alkyl, C1-C6-alkoxy, and/or trimethylsilyl, and R1 to R4, independently of one another, are each hydrogen, C1-C10-alkyl, C1-C10-alkoxy, F, Cl, or Br.
