Double lithiation of bis(tetra-hydroindenyl)iron followed by phosphorylation using PhzPCl affords two different chiral diphosphines having respectively Ct-and Ca-symmetry. Following antipode separation, the compounds can be used as ligands in Rh-catalyzed hydrogenation (up to 97% ee) and hydroborati
