Several 1,6-enynes have been chosen as model substrates affording moderate yields and selectivities of up to 86% ee. Besides binap-type ligands, we have demonstrated that the Pstereogenic C1-symmetry small-bite-angle ligand MaxPHOS is a viable ligand in this process. The formation of [2+2+2] cycloaddition compounds has shown to be a competitive process. A mechanism is proposed to account for the observed results. The intermediate rhodium dicarbonyl complex 6 was synthesized, and its solid-state structure was elucidated by X-ray crystallography.5 p.application/pdfengcc-by-nc (c) American Chemical Society , 2015http://creativecommons.org/licenses/by-nc/3.0/esLligandsCatàlisi asimètricaRodiReacció de Pauson-KhandLigandsEnantioselective catalysisRhodiumPauson-Khand reactioninfo:eu-repo/semantics/article6552122016-02-08info:eu-repo/semantics/openAccess
