title: Manganese- and cobalt-based coordination networks as promising heterogeneous catalysts for olefin epoxidation reactions.
abstract: We demonstrate the synthesis of Mn(2+)- and Co(2+)-based coordination networks using two Co(3+)-based metalloligands differing by the position of the appended arylcarboxylate groups. The structural analyses reveal topologically distinct networks with pores of variable dimensions allowing facile diffusion of substrates and/or reagents. All four networks function as heterogeneous catalysts for the olefin epoxidation reactions using tert-butyl-hydroperoxide without any requirement of solvent or additive. Control and optimization experiments illustrate recyclable network-based catalysts that make them attractive candidates for the "greener" oxidation chemistry processes.
