A thorough structural analysis of the resulting PK adducts has been carried out to unveil that α-trifluoromethylcyclopentenones are preferred in all cases, independently of the electronic properties of the alkyne. The regioselectivity observed with norbornadiene and ethylene is higher than in the case of norbornene.12 p.application/pdfengcc-by (c) Aiguabella Font, Núria et al., 2014http://creativecommons.org/licenses/by/3.0/esCiclització (Química)Química organometàl·licaCobaltRing formation (Chemistry)Organometallic chemistryCobaltinfo:eu-repo/semantics/article6334582014-05-22info:eu-repo/semantics/openAccess24496269
