A simple way of recycling of homogeneous catalyst in Suzuki reaction

Abstract

A simple and practical method of recycling homogeneous catalysts in the Suzuki reaction using appropriate work up conditions is reported here. The commonly used and commercially available homogeneous catalysts 1 (Pd-100) dichlorobis(tri-phenylphosphine)palladium(II), 2 (Pd-106) dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II)-dichloromethane adduct, and 3 (Pd-118) 1,1′-bis(di-tert-butylphosphino)ferrocene]dichloropalladium(II) selected for our study and were recycled successfully for three times using simple acidic and basic work up conditions depending on the presence of amino or carboxylic acid functional group in the product.
