Abstract

High-valent tetraphenylporphyrinatotin(IV) triflate, [Sn IV(TPP)(OTf)2], was found as an efficient catalyst for the coupling of several epoxides (linear and cyclic) with carbon dioxide in the presence of tetrabutylphosphonium bromide as co-catalyst at atmospheric pressure. The reaction temperature, kind of solvent, co-catalyst and axial ligand effect were also investigated. © 2011 Elsevier B.V. All rights reserved.
