The present invention relates to bis-aminophosphines which are useful as catalysts for the dimerization of
alkyl acrylates. Furthermore, the present invention relates to a process for preparing bis-aminophophines, the use of these bis-aminophosphines as catalysts for dimerization reaction of
alkyl acrylates and a process for obtaining dimers of
alkyl acrylates using bis-aminophosphines as catalyst.
