Cover Picture: Cu and Au Metal–Organic Frameworks Bridge the Gap between Homogeneous and Heterogeneous Catalysts for Alkene Cyclopropanation Reactions (Chem. Eur. J. 32/2010)

Abstract

Metal–Organic Framework (MOF) materials containing either Cu or Au centers can act as catalysts for the cyclopropanation of alkenes with diazoacetates. In their Full Paper on on page 9789 ff., A. Corma et al. describe Cu and Au MOFs that are active and reusable heterogeneous catalysts for cycloproponation of alkenes with high chemo- and diastereoselectivities. This example is the first use of these materials to induce the carbene transfer reactions from diazo compounds.
