Abstract

A rhodium-DIOP complex attached to a macroporous silica gel has been tested as catalyst for the enantioselective hydrosilylation of acetophenone and hydrogenation of α-acetamidocinnamic acid. The catalyst has been found to be comparable in asymmetric efficiency to homogeneous analogues. In both reactions, the activity of the heterogenized catalyst was by ca. one order of magnitude lower relative to the homogeneous system.

Abstract

Каталитические свойства комплекса родия с DIOP, связанного на макропористом силикагеле, были проверены в энантиоселективном гидросилилировании ацетофчнона и гидрировании α-ацетамидокоричной кислоты. Было найдено, что катализатор по своей асимметричной эффективности сравним с гомогенными аналогами. В обоих реакциях активность гетерогенного катализатора была приблизительно на один порядок ниже по сравнению с гомогенными системами.
