Abstract

Double lithiation of bis(tetra-hydroindenyl)iron followed by phosphorylation using Ph 2 PCl affords two different chiral diphosphines having respectively C 1 - and C 2 -symmetry. Following antipode separation, the compounds can be used as ligands in Rh-catalyzed hydrogenation (up to 97% ee ) and hydroboration (up to 84% ee ) of olefins and in Ir-catalyzed hydrogenation of imines (up to 79% ee ).
