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 http://hdl.handle.net/10256/19748 Ful·lerens Fullerenes Catàlisi Catalysis Addition reactions Reaccions d'addició Funcional de densitat, Teoria del Density functionals Cèl·lules solars Solar cells Synthesis of Fused Dihydroazepine Derivatives of Fullerenes by a Rh-Catalyzed Cascade Process
