title: Catalysts with mixed ligands on immobilized supports. Electronic and steric advantages.
abstract: [reaction: see text] Immobilized dirhodium(II) catalysts having mixed chiral ligands enhance reactivity (AH = azetidinone) and influence stereoselectivity in cyclopropanation and carbon-hydrogen insertion reactions.
