ChemInform Abstract: Novel Half‐Sandwich η5‐Cp*—Rhodium(III) and η5‐Cp*—Ruthenium(II) Complexes Bearing Bis(phosphino)amine Ligands and Their Use in the Transfer Hydrogenation of Aromatic Ketones.

Abstract

Two new half-sandwich η5-Cp*–rhodium(III) and η5-Cp*–ruthenium(II) complexes have been prepared from corresponding bis(phosphino)amine ligands, thiophene-2-(N,N-bis(diphenylphosphino)methylamine) or furfuryl-2-(N,N-bis(diphenylphosphino)amine). Structures of the new complexes have been elucidated by multinuclear one- and two-dimensional NMR spectroscopy, elemental analysis and IR spectroscopy. These Cp*–rhodium(III) and Cp*-ruthenium(II) complexes bearing bis(phosphino)amine ligands were successfully applied to transfer hydrogenation of various ketones by 2-propanol.
