Treatment of a toluene solution of 2 with 2-vinylpyridine leads to the 1,2-dihydro-3-ruthenaindolizine derivative tiebar above startRu(CH2CH2−C5H4tiebar above endN)Tp(PiPr3) (3). Complex 3 aromatizes in toluene at 80 °C to afford the 3-ruthenaindolizine complex tiebar above startRu(CHCH−C5H4tiebar above endN)Tp(PiPr3) (4) by loss of a hydrogen molecule in the absence of any hydrogen acceptor. The aromatic character of 4 is supported by X-ray diffraction analysis, NMR spectroscopy, and DFT calculations. 000131133 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E35$$9info:eu-repo/grantAgreement/ES/MICINN/CSD2007-00006$$9info:eu-repo/grantAgreement/ES/MICINN/CTQ2008-00810 000131133 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000131133 590__ $$a4.204$$b2009 000131133 591__ $$aCHEMISTRY, ORGANIC$$b9 / 57 = 0.158$$c2009$$dQ1$$eT1 000131133 591__ $$aCHEMISTRY, INORGANIC & NUCLEAR$$b4 / 44 = 0.091$$c2009$$dQ1$$eT1 000131133 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000131133 700__ $$aFernández, Israel 000131133 700__ $$0(orcid)0000-0003-1812-3175$$aFuertes, Sara 000131133 700__ $$0(orcid)0000-0001-7183-4975$$aLópez, Ana M.$$uUniversidad de Zaragoza 000131133 700__ $$0(orcid)0000-0003-2094-719X$$aOñate, Enrique 000131133 700__ $$aSierra, Miguel A. 000131133 7102_ $$12010$$2760$$aUniversidad de Zaragoza$$bDpto.
