A Polymer‐Supported Chiral Dirhodium(II) Complex: Highly Durable and Recyclable Catalyst for Asymmetric Intramolecular CH Insertion Reactions

Abstract

A highly effective immobilization of [Rh2(S-PTTL)4] (PTTL=N-phthaloyl-tert-leucinate) has been achieved by copolymerization of monomer 1 with styrene and a flexible cross-linker. The immobilized catalyst promoted the title reaction at −78 °C with high enantioselectivity, and could be used for up to 100 cycles with a low level of leaching (0.28 ppm).
