Rhodium-grafted hydrotalcite catalyst for heterogeneous 1,4-addition reaction of organoboron reagents to electron deficient olefins†
Abstract
A rhodium-grafted hydrotalcite (Rh/HT) was prepared by the treatment of a Mg–Al mixed hydroxide (hydrotalcite, HT) with an aqueous RhCl3·nH2O solution. The formation of the RhIII species on the HT surface was confirmed by
