The photoreaction system exhibits a wide substrate scope and the potential for large-scale applications. Most of the desired products are easily obtained via recrystallization and separation from low-boiling reaction medium acetone in good yields, and the products can be subsequent directly transformed without further purification.<\/jats:p>","DOI":"10.3390\/molecules28073031","type":"journal-article","created":{"date-parts":[[2023,3,29]],"date-time":"2023-03-29T01:33:00Z","timestamp":1680053580000},"page":"3031","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["External Catalyst- and Additive-Free Photo-Oxidation of Aromatic Alcohols to Carboxylic Acids or Ketones Using Air\/O2"],"prefix":"10.3390","volume":"28","author":[{"given":"Meng","family":"Xu","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, Hunan Institute of Technology, Hengyang 421002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinhua","family":"Ou","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Hunan Institute of Technology, Hengyang 421002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kejun","family":"Luo","sequence":"additional","affiliation":[{"name":"Analytical Testing Center, Changsha Research Institute of Mining and Metallurgy Co., Ltd., Changsha 410012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rongtao","family":"Liang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Hunan Institute of Technology, Hengyang 421002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Hunan Institute of Technology, Hengyang 421002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ni","family":"Li","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Hunan Institute of Technology, Hengyang 421002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bonian","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Hunan Institute of Technology, Hengyang 421002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaijian","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Hunan Institute of Technology, Hengyang 421002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1023","DOI":"10.1055\/s-0040-1706102","article-title":"Direct Oxidation of Primary Alcohols to Carboxylic Acids","volume":"53","author":"Cherepakhin","year":"2021","journal-title":"Synthesis"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"6738","DOI":"10.1021\/acscatal.8b01640","article-title":"Electrochemical oxidation of alcohols and aldehydes to carboxylic acids catalyzed by 4-acetamido-TEMPO: An alternative to \u201cAnelli\u201d and \u201cPinnick\u201d oxidations","volume":"8","author":"Rafiee","year":"2018","journal-title":"ACS Catal."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"6486","DOI":"10.1021\/acssuschemeng.9b00427","article-title":"Direct microdroplet synthesis of carboxylic acids from alcohols by preparative paper spray ionization without phase transfer catalysts","volume":"7","author":"Zhu","year":"2019","journal-title":"ACS Sustain.
