The catalyst operates in the absence of ligands such as halides and shows high selectivity to n-butenes, even in an excess of H2.Reserva de todos los derechosAlkene dimerizationBifunctional catalysisC[BOND]C bond formationRhodium complexesZeolitesA Bifunctional Mechanism for Ethene Dimerization: Catalysis by Rhodium Complexes on Zeolite HY in the Absence of HalidesArtÃculo10.1002/anie.201008086Cerrado21538737
