Amberlyst\u201015 in the dry form promoted the one\u2010step formation of hydroquinone from quinic acid in toluene without any oxidants or metal catalysts in 72\u2009% yield. Several acidic polymer\u2010based resins and organic acids as promoters as well as a variety of reaction conditions were screened including temperature, concentration and low\u2010 and high\u2010boiling\u2010point solvents. A 1:4 (w\/w) ratio of quinic acid\/Amberlyst\u201015 was determined to be optimal to promote hydroquinone formation with only traces of a dimeric side\u2010product. A mechanism has been proposed based on the decarbonylation of protonated quino\u20101,5\u2010lactone that is supported by experimental and computational calculation data.<\/jats:p>","DOI":"10.1002\/ejoc.201600616","type":"journal-article","created":{"date-parts":[[2016,7,14]],"date-time":"2016-07-14T12:10:48Z","timestamp":1468498248000},"page":"3856-3861","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Biomass\u2010Based and Oxidant\u2010Free Preparation of Hydroquinone from Quinic Acid"],"prefix":"10.1002","volume":"2016","author":[{"given":"Benedicta","family":"Assoah","sequence":"first","affiliation":[{"name":"Department of Chemistry and Bioengineering Tampere University of Technology  Korkeakoulunkatu 8 33101 Tampere Finland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5841-3519","authenticated-orcid":false,"given":"Luis F.","family":"Veiros","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica Estrutural Instituto Superior T\u00e9cnico Universidade de Lisboa  Av.
