New magnetically recoverable palladium-based catalysts active in the alkoxycarbonylation of iodobenzene

Abstract

New magnetically recoverable catalysts have been synthesized by deposition of 1 % palladium (Pd)-metal on the polymer poly(1-oxo-trimethylene), containing 15 % of magnetite. The magnetite allows the complete recovery of the catalyst with the simple application of an external magnetic field. The activity of such a catalyst has been studied under phosphine-free conditions in the alkoxycarbonylation of iodobenzene to the corresponding benzoic acid esters
