CSIC ORCID | Fecha de publicación: | 2014 | Editor: | American Chemical Society | Citación: | Organometallics 33(3): 616-619 (2014) | Resumen: | The phosphane-hydroxyl ligand (SC1,RC2)-Ph 2PC(Ph)HC(OH)HCH2OMe (POH) displays κ1P, κ2P,O, κ3P,O,O′, and anionic deprotonated κ3P,O,O′ coordination modes toward the metallic (η6-p-MeC6H4iPr)Ru moiety. The hydroxyl group in [(η6-p-MeC6H4iPr) Ru(κ3P,O,O′-POH)][SbF6]2 (3) has strong acidic properties. This complex catalyzes the Diels-Alder reaction between cyclopentadiene and trans-β-nitrostyrene or methacrolein as well as the Friedel-Crafts reaction between indole and methyl 3,3,3,-trifluoropyruvate or trans-β-nitrostyrene. Solution studies strongly indicate that complex 3 acts as a metallic Lewis acid assisted Brønsted-acid catalyst. © 2014 American Chemical Society. | URI: | http://hdl.handle.net/10261/92784 | DOI: | 10.1021/om401215m | Identificadores: | doi: 10.1021/om401215m issn: 0276-7333 e-issn: 1520-6041 |
