Only the monoalkylated adduct was obtained in all cases with enantioselectivities of up to 93/7 e.r. Solution NMR measurements have allowed us to detect and characterise catalytic intermediates such as metal-trans-β-nitrostyrene and metal‑aci-nitro complexes, as well as free aci‑nitro compound. Based on these studies, a Michael-type Friedel-Crafts mechanism is proposed. info:eu-repo/grantAgreement/ES/DGA/E05-23R info:eu-repo/grantAgreement/ES/MCIU-AEI-FEDER/PID2021-122406NB-I00 info:eu-repo/grantAgreement/ES/MCIU/CTQ2018-095561-BI00 info:eu-repo/semantics/openAccess by-nc https://creativecommons.org/licenses/by-nc/4.0/deed.es 2.4 2024 CHEMISTRY, ORGANIC 21 / 57 = 0.368 2024 Q2 T2 CHEMISTRY, INORGANIC & NUCLEAR 22 / 43 = 0.512 2024 Q3 T2 0.385 2024 Biochemistry 2024 Q3 Inorganic Chemistry 2024 Q3 Physical and Theoretical Chemistry 2024 Q3 Organic Chemistry 2024 Q3 Materials Chemistry 2024 Q3 4.1 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Sánchez, Antonio Viguri, Fernando Universidad de Zaragoza (orcid)0000-0002-6160-3046 Rodríguez, Ricardo (orcid)0000-0002-8845-0174 Lamata, Pilar Universidad de Zaragoza (orcid)0000-0001-9071-563X Carmona, Daniel 2010 760 Universidad de Zaragoza Dpto.
