With an electron-donating group (EDG), such as alkoxy or amino-functionalized phenols as reaction partners, the 7-aryloxy benzofurans have been furnished via benzofuran annulation and aryl C\u2013H aryloxylation. On the other hand, using hydroquinone as a reaction partner under slightly modified conditions allows the selective synthesis of 5-hydroxy benzofurans. Importantly, the cyclic voltammetry (CV) experiments confirm that hexafluoroisopropanol (HFIP) plays a crucial role in the titled reaction by lowering the oxidation potential of phenol substrates.<\/jats:p>","DOI":"10.1021\/acs.joc.6c01939","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T01:18:28Z","timestamp":1790212708000},"page":"13518-13524","source":"Crossref","is-referenced-by-count":0,"title":["HFIP-Assisted Electrochemical\nAnnulation of Enaminones\nwith Phenols for the Selective Synthesis of 7-Aryloxy and 5-Hydroxy\nBenzofurans"],"prefix":"10.1021","volume":"91","author":[{"given":"Yangxiu","family":"Liao","sequence":"first","affiliation":[{"name":"Jiangxi Normal University , , ,","place":["Nanchang, China, 330022"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5553-1672","authenticated-orcid":true,"given":"Yunyun","family":"Liu","sequence":"additional","affiliation":[{"name":"Jiangxi Normal University , , ,","place":["Nanchang, China, 330022"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quanquan","family":"Zhou","sequence":"additional","affiliation":[{"name":"Jiangxi Normal University , , ,","place":["Nanchang, China, 330022"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6463-2937","authenticated-orcid":true,"given":"Weijun","family":"Yao","sequence":"additional","affiliation":[{"name":"Zhejiang Sci-Tech University , , ,","place":["Hangzhou, China, 310018"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9367-8384","authenticated-orcid":true,"given":"Jie-Ping","family":"Wan","sequence":"additional","affiliation":[{"name":"Jiangxi Normal University , , ,","place":["Nanchang, China, 330022"]},{"name":"Nanjing Forestry University , , ,","place":["Nanjing, China, 210037"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"2026100909092013600_cit1a","doi-asserted-by":"publisher","first-page":"483","DOI":"10.1016\/j.ejmech.2014.11.039","article-title":"Bioactive Benzofuran derivatives: A review","volume":"97","author":"Khanam","year":"2015","journal-title":"Eur.
