Selective photooxidation of sulfides catalyzed by bis‐cyclometalated IrIII photosensitizers bearing 2,2′‐dipyridylamine‐based ligands Vaquero Gutiérrez, Mónica Ruiz Riaguas, Alba Martínez Alonso, Marta Jalón Sotés, Félix Ángel Manzano, Blanca R. . Rodríguez, Ana M. . García Herbosa, Gabriel Carbayo Martín, Mª Aránzazu García Ruiz, Begoña Espino Ordóñez, Gustavo A new family of heteroleptic bis-cyclometalated IrIII complexes with formula [Ir(C _ N)2(N _ N)]Cl (C _ N=2-phenylpyridinate and N _ N=2,2’-dipyridylamine or N-benzylated 2,2’-dipyridylamines, were synthesized, characterized, and successfully used as photosensitizers in the catalytic photooxidation of an array of dialkyl, dibenzyl, alkyl aryl, and diaryl sulfides, as well as sulfur-containing amino acids. Furthermore, the reactions proceeded with optimal chemoselectivity, and atom economy under mild conditions. Experimental observations support a dual mechanism in which singlet oxygen and superoxide are the actual oxidants. 2018-08-27T08:18:09Z 2019-07-25T02:45:07Z 2018-07 info:eu-repo/semantics/article 0947-6539 http://hdl.handle.net/10259/4885 10.1002/chem.201801173 eng Chemistry-a european journal. 2018, V. 24, n. 42, p. 10662-10671 https://doi.org/10.1002/chem.201801173 info:eu-repo/grantAgreement/JCyL/BU042U16 info:eu-repo/grantAgreement/MINECO/CTQ2014-58812-C2-1-R info:eu-repo/grantAgreement/MINECO/CTQ2014-58812-C2-2-R info:eu-repo/grantAgreement/MINECO/CTQ2015-70371-REDT info:eu-repo/grantAgreement/FundaciónLaCaixa/OSLC-2012-007 info:eu-repo/semantics/openAccess Wiley-VCH Verlag
