  text: A novel immobilized chiral dirhodium catalyst, Rh2(S-PTTL)3(S-PTTL-linker)∼SBA-15
    (8), has been prepared via click reaction of azide-groups on functionalized SBA-15
    with the dirhodium complex Rh2(S-PTTL)3(S-PTTL-alkyne) (6) containing an alkyne
    moiety. During the synthesis of this complex, one chiral ligand of the parent
    Rh2(S-PTTL)4 catalyst is exchanged with an analogous chiral ligand system containing
    an alkyne moiety, which to a great extent maintains the intrinsic catalytic performance
    of the catalyst. The heterogeneous dirhodium catalyst is characterized by FT-IR
    and 13C solid-state NMR to validate the successful immobilization. The catalytic
    performance of the heterogeneous catalyst 8 is investigated in the asymmetric
    cyclopropanation of 3-diazooxindole with different aryl alkenes that form spiro-cyclopropyloxindoles
    which serve as precursors for pharmaceuticals. The resulting heterogeneous catalyst
    shows high catalytic activity and significant enantioselectivity. Importantly,
    it can be readily recovered and reused at least four times without significant
    loss of its catalytic performance.
