The reactions of 2-cyclohexylidenecyclohexanone oxide in the presence of (i) sulfuric acid, (ii) fluorosulfonic acid, (iii) boron trifluoride etherate, and (iv) antimony pentachloride have been studied. The products consisted of spiro[5.6]dodecane-7,12-dione, 2-(1-cyclohexenyl)-2-hydroxycyclohexanone, and 1,2,3,4,6,7,8,9-octahydrodibenzofuran. The ratio of the products was found to depend on the differences
已经研究了 2-亚环己基环己酮氧化物在 (i) 硫酸、(ii) 氟磺酸、(iii) 三氟化硼醚合物和 (iv) 五氯化锑存在下的反应。产物由螺[5.6]十二烷-7,12-二酮、2-(1-环己烯基)-2-羟基环己酮和1,2,3,4,6,7,8,9-八氢二苯并呋喃组成。发现产物的比例取决于催化剂和溶剂的差异。
