Synthesis of Fused Dihydroazepine Derivatives of Fullerenes by a Rh-Catalyzed Cascade Process Artigas Ruf, Albert Castanyer, Cristina Roig, Nil Lledó Ponsati, Agustí Solà i Puig, Miquel Pla i Quintana, Anna Roglans i Ribas, Anna Agencia Estatal de Investigación Ful·lerens Fullerenes Catàlisi Catalysis Addition reactions Reaccions d'addició Funcional de densitat, Teoria del Density functionals Cèl·lules solars Solar cells A synthetic methodology is reported that functionalizes C60 and C70 fullerenes with dihydroazepine rings by a cascade reaction encompassing a rhodium-catalyzed cycloisomerization of 1,5-bisallenes and a [4+2] cycloaddition. This transition metal-catalyzed cascade reaction provides a versatile and step-economical approach to the synthesis of 6,7-membered polyheterocyclic fullerene adducts. Electrochemical characterization of the products obtained ventures their application in organic and perovskite photovoltaic devices We are grateful for the financial support by the Spanish Ministry of Economy and Competitivity (MINECO) (Projects CTQ2017-85341-P and CTQ2017-83587-P, FPI predoctoral grant to A.A. and C.C.) and the Generalitat de Catalunya (Project 2017-SGR-3 Open Access funding provided thanks to the CRUE-CSIC agreement with Wiley 2021-08-03 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion peer-reviewed http://hdl.handle.net/10256/19748 http://hdl.handle.net/10256/19748 eng info:eu-repo/semantics/altIdentifier/doi/10.1002/adsc.202100644 info:eu-repo/semantics/altIdentifier/issn/1615-4150 info:eu-repo/semantics/altIdentifier/eissn/1615-4169 info:eu-repo/grantAgreement/AEI/Plan Estatal de Investigación Científica y Técnica y de Innovación 2013-2016/CTQ2017-85341-P/ES/AVANCES EN LA REACTIVIDAD DE FULLERENOS Y NANOTUBOS: ESTUDIOS TEORICO-EXPERIMENTALES DE CICLACIONES CATALIZADAS POR METALES DE TRANSICION/ info:eu-repo/grantAgreement/AEI/Plan Estatal de Investigación Científica y Técnica y de Innovación 2013-2016/CTQ2017-83587-P/ES/CATALISIS BIOMIMETICA DE CICLACIONES CARBOCATIONICAS CON RECEPTORES SINTETICOS/ Attribution-NonCommercial-NoDerivatives 4.0 International http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess application/pdf Wiley Advanced Synthesis & Catalysis (ASC), 2021, vol. 363, núm. 15, p. 3835-3844 Articles publicats (D-Q)
