This novel compound is transformed into a hydroxyalkenylcarbene isomer by deprotonation and subsequent protonation of the resulting α,β-unsaturated acyl transient species. In fluorobenzene at 90 °C, the four-membered ring undergoes cycloreversion to afford a cis-dicarbonyl derivative and the cycloalkene. 000165306 540__ $$9info:eu-repo/semantics/closedAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000165306 590__ $$a4.145$$b2012 000165306 591__ $$aCHEMISTRY, ORGANIC$$b11 / 57 = 0.193$$c2012$$dQ1$$eT1 000165306 591__ $$aCHEMISTRY, INORGANIC & NUCLEAR$$b6 / 44 = 0.136$$c2012$$dQ1$$eT1 000165306 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000165306 700__ $$0(orcid)0000-0002-4829-7590$$aEsteruelas, M.A.$$uUniversidad de Zaragoza 000165306 700__ $$0(orcid)0000-0002-5545-5112$$aGarcía-Yebra, C.$$uUniversidad de Zaragoza 000165306 700__ $$0(orcid)0000-0003-2094-719X$$aOñate, E. 000165306 7102_ $$12010$$2760$$aUniversidad de Zaragoza$$bDpto.
