摘要: Use of a rhodium catalyst with electron-rich and bulky chiral diphosphine ligands having C2-symmetry allowed efficient dehydrogenative silylation the C(sp2)–H bond ferrocenes leading to benzosiloloferrocenes. The substrate scope was expanded hydrogermane hydrosilanes ruthenocene backbone, which resulted in new approach benzosilole- benzogermole-fused metallocenes.
