Copper(I) complexes with different ligands were applied in combination with [Ru(bipy)<jats:sub>3<\/jats:sub>](PF<jats:sub>6<\/jats:sub>)<jats:sub>2<\/jats:sub> and dioxygen as the oxidant. As a result, a \u201cdioxygen adduct\u201d copper complex, for example, a peroxido complex, is formed as the active species. The copper(II) complex obtained after oxidation can be photochemically reduced to the starting copper(I) species, and the process can be repeated continuously. The ligand tris(2\u2010methylpyridyl)amine (tmpa) led to the highest conversion rates.<\/jats:p>","DOI":"10.1002\/chem.202301142","type":"journal-article","created":{"date-parts":[[2023,5,17]],"date-time":"2023-05-17T07:05:52Z","timestamp":1684307152000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Photochemically Mediated Toluene Oxidation through a Copper Complex"],"prefix":"10.1002","volume":"29","author":[{"given":"Christian","family":"No\u00df","sequence":"first","affiliation":[{"name":"Institute for Inorganic and Analytical Chemistry Justus-Liebig-University Gie\u00dfen  Heinrich-Buff-Ring 17 35392 Gie\u00dfen Germany"},{"name":"Institute for Organic Chemistry Justus-Liebig-University Gie\u00dfen  Heinrich-Buff-Ring 17 35392 Gie\u00dfen Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1424-3084","authenticated-orcid":false,"given":"Richard","family":"G\u00f6ttlich","sequence":"additional","affiliation":[{"name":"Institute for Organic Chemistry Justus-Liebig-University Gie\u00dfen  Heinrich-Buff-Ring 17 35392 Gie\u00dfen Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9991-9513","authenticated-orcid":false,"given":"Siegfried","family":"Schindler","sequence":"additional","affiliation":[{"name":"Institute for Inorganic and Analytical Chemistry Justus-Liebig-University Gie\u00dfen  Heinrich-Buff-Ring 17 35392 Gie\u00dfen Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,6,29]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"crossref","first-page":"11","DOI":"10.1080\/10915810600716612","volume":"25","author":"Andersen A.","year":"2006","journal-title":"Int.
