Samarium trifluoromethanesulfonate (Sm(OTf) 3 ) was found to be a novel catalyst for synthesis of diphenyl carbonate (DPC) by transesterification of dimethyl carbonate (DMC) with phenol. The best result was obtained by using Sm(OTf) 3 catalyst. The TON reached 21.8 mol DPC/mol Sm when the reaction w
