Unlocking the Continuous Flow Asymmetric Hydrogenation of Olefins Through the Development of a Non‐Deactivating Immobilized Iridium Catalyst

open access: yesAngewandte Chemie, EarlyView.
We have developed stable, robust, and reusable heterogeneous metal catalysts for an efficient continuous flow asymmetric hydrogenation (AH) of a variety of olefins, far beyond the typical benchmark AH. The products are produced continuously over long periods of time with high catalytic performance (up to 99% ee).
