In the case of reactions with N-methyl 2-pyrrolyl \u03b1,\u03b2-unsaturated ketones, the major product was the insertion derivative. However, in the reactions of 2-thiophenyl and 2-furyl \u03b1,\u03b2-unsaturated ketones with dimethyl diazomalonate (acceptor-acceptor disubstituted), only dihydrofuran products were formed over carbonyl ylides. When 2-thiophenyl and 2-furyl \u03b1,\u03b2-unsaturated ketones were reacted with 1-diazo-1-phenyl-propane-2-one (donor-acceptor disubstituted), 1-phenylpropane-1,2-dione was obtained under our reaction conditions.<\/jats:p>","DOI":"10.55730\/1300-0527.3625","type":"journal-article","created":{"date-parts":[[2024,1,5]],"date-time":"2024-01-05T16:47:30Z","timestamp":1704473250000},"page":"1429-1437","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of metal-carbenoid reactions of \u03b2-2-five-membered heteroaryl substituted \u03b1,\u03b2-unsaturated ketones"],"prefix":"10.55730","volume":"47","author":[{"given":"KUMSAL","family":"ERO\u011eLU","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"OLCAY","family":"ANA\u00c7","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F\u00dcSUN \u015eEYMA","family":"KI\u015eKAN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"34691","published-online":{"date-parts":[[2023,12,29]]},"container-title":["Turkish Journal of Chemistry"],"original-title":[],"language":"en","deposited":{"date-parts":[[2026,10,21]],"date-time":"2026-10-21T12:56:22Z","timestamp":1792587382000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.tubitak.gov.tr\/chem\/vol47\/iss6\/12"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,12,29]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2023,12,29]]}},"URL":"https:\/\/doi.org\/10.55730\/1300-0527.3625","relation":{},"ISSN":["1300-0527"],"issn-type":[{"value":"1300-0527","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,12,29]]}}}
