In ferrocene diphosphines of formula (I), in which R represents, for example, methyl or phenyl, the catalytic properties of corresponding metal complexes can, in many instances, be distinctly influenced by structural changes on one or both of the CP rings, and the catalytic reaction with regard to selected substrates can be optimized and significantly improved. Diphosphine ligands of this type are accessible by using novel production methods.

L'invention concerne des diphosphènes de ferrocène de formule (I), dans laquelle R désigne par exemple méthyle ou phényle. Dans de nombreux cas, les propriétés catalytiques de complexes métalliques correspondants peuvent être nettement influencées par des modifications de structure. La réaction catalytique en termes de substrats sélectionnés est nettement optimisée et sensiblement améliorée. De tels ligands de diphosphine peuvent être accessibles par l'intermédiaire de nouveaux procédés de production.
