This convenient one-pot synthetic strategy has several advantages, including being transition-metal-free, having no extra additives or reagents, having a broad substrate scope, having a high isolated yield, having a minimum amount of base employment, having a shorter reaction time, use of cheap starting materials, cost-effectiveness, and being environment friendly. Some of the chemical structures of 1,5-diketones were confirmed by X-ray single-crystal diffraction analysis. The application of 1,5-diketones was demonstrated in the preparation of 2,4,6-triaryl pyridine derivatives under a catalyst-free system using ammonium acetate as a nitrogen source.<\/jats:p>","DOI":"10.1021\/acsomega.0c05328","type":"journal-article","created":{"date-parts":[[2021,3,9]],"date-time":"2021-03-09T13:31:12Z","timestamp":1615296672000},"page":"7296-7311","source":"Crossref","is-referenced-by-count":25,"title":["One-Pot Synthesis of 1,5-Diketones under a Transition-Metal-Free\nCondition: Application in the Synthesis of 2,4,6-Triaryl Pyridine\nDerivatives"],"prefix":"10.1021","volume":"6","author":[{"given":"Kesatebrhan\nHaile","family":"Asressu","sequence":"first","affiliation":[{"name":"Academia Sinica , , ,","place":["Taipei, Taiwan, 115"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chieh-Kai","family":"Chan","sequence":"additional","affiliation":[{"name":"Academia Sinica , , ,","place":["Taipei, Taiwan, 115"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2562-0658","authenticated-orcid":true,"given":"Cheng-Chung","family":"Wang","sequence":"additional","affiliation":[{"name":"Academia Sinica , , ,","place":["Taipei, Taiwan, 115"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2021,3,9]]},"reference":[{"key":"2026081415071369400_cit1","doi-asserted-by":"publisher","first-page":"5665","DOI":"10.1021\/acs.joc.8b00666","article-title":"Intermolecular\nOxidative Radical Addition to Aromatic Aldehydes: Direct Access to\n1,4- and 1,5-Diketones via Silver-Catalyzed Ring-Opening Acylation\nof Cyclopropanols and Cyclobutanols","volume":"83","author":"Che","year":"2018","journal-title":"J.
