Abstract

Surface hydroxyl groups on porous and nonporous metal oxides, such as silica gel and alumina, were metalated with catalyst precursors, such as complexes of earth abundant metals (e.g., Fe, Co, Cr, Ni, Cu, Mn and Mg). The metalated metal oxide catalysts provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of organic transformations. The catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.
