Surface functionalization of metal–organic polyhedron for homogeneous cyclopropanation catalysis

Abstract
A super-paddlewheel (comprised of two paddlewheels) metal–organic polyhedron (MOP) containing surface hydroxyl groups was synthesized and characterized. Condensation reactions with linear alkyl anhydrides lead to new MOPs with enhanced solubility. As a result, the surface-modified MOP 4 was demonstrated as a homogeneous Lewis-acid catalyst.
