Use of a rhodium catalyst with electron-rich and bulky chiral diphosphine ligands having C 2 -symmetry allowed efficient dehydrogenative silylation of the C(sp 2 )-H bond of ferrocenes leading to chiral benzosiloloferrocenes. The substrate scope was expanded to hydrogermane and hydrosilanes having a ruthenocene backbone, which resulted in a new approach to benzosilole- and benzogermole-fused metallocenes.
