In this study, we present two highly effective catalytic protocols for the cleavage of C\u2013O bonds in lignin \u03b1-O-4 model compounds under mild conditions (100 \u00b0C) that do not require organic solvents. Benzyl phenyl ether and its derivatives undergo quantitative conversion at 100 \u00b0C in the absence of an organic solvent under two contrasting conditions: aqueous trifluoromethanesulfonic acid (TfOH) yields the hydrolysis products phenol and benzyl alcohol, whereas solid superacid Nafion NR50 yields benzyl-migrated recombination products predominantly under solvent-free conditions. Nafion NR50 was recovered and reused for five consecutive cycles with conversion maintained within experimental error of activity. Non-fluorinated resins undergo the same transformation more slowly, which suggests that a perfluorinated acid is unnecessary. The medium-control principle established here defines the conditions under which condensation can be suppressed during acid-mediated \u03b1-O-4 cleavage.<\/jats:p>","DOI":"10.1021\/acsomega.6c05568","type":"journal-article","created":{"date-parts":[[2026,10,2]],"date-time":"2026-10-02T01:01:27Z","timestamp":1790902887000},"page":"61291-61298","source":"Crossref","is-referenced-by-count":0,"title":["Hydrolysis of Lignin\n\u03b1-O-4 Model\nCompounds Using Strong Acid Catalyst in Water"],"prefix":"10.1021","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7071-3642","authenticated-orcid":true,"given":"Shota","family":"Mizuno","sequence":"first","affiliation":[{"name":"Gifu University , , 1-1, Yanagido , ,","place":["Gifu, Japan, 501-1193"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koshiro","family":"Yamaguchi","sequence":"additional","affiliation":[{"name":"Gifu University , , 1-1, Yanagido , ,","place":["Gifu, Japan, 501-1193"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9177-4364","authenticated-orcid":true,"given":"Yasuhiro","family":"Kubota","sequence":"additional","affiliation":[{"name":"Gifu University , , 1-1, Yanagido , ,","place":["Gifu, Japan, 501-1193"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiyasu","family":"Inuzuka","sequence":"additional","affiliation":[{"name":"Gifu University , , 1-1 Yanagido , ,","place":["Gifu, Japan, 501-1193"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7880-6093","authenticated-orcid":true,"given":"Kazumasa","family":"Funabiki","sequence":"additional","affiliation":[{"name":"Gifu University , , 1-1, Yanagido , ,","place":["Gifu, Japan, 501-1193"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,1]]},"reference":[{"key":"2026101315065454700_cit1","doi-asserted-by":"publisher","first-page":"690","DOI":"10.1126\/science.1217501","article-title":"Challenges\nin metal recycling","volume":"337","author":"Reck","year":"2012","journal-title":"Science"},{"key":"2026101315065454700_cit2","doi-asserted-by":"publisher","first-page":"10502","DOI":"10.1002\/anie.201102117","article-title":"Beyond petrochemicals:\nthe renewable chemicals industry","volume":"50","author":"Vennestr\u00f8m","year":"2011","journal-title":"Angew.
