ketones were synthesized from the reaction of acid chlorides and acetylenic compounds in the presence of ZnBr2 and DIEA in acetonitrile. From the acetylenic ketones having nearby methylene unit, 2,5-disubstituted furan derivatives could be synthesized under the same reaction conditions.
α,β -炔酮从酰氯和炔化合物的在ZnBr的存在下反应,合成2和DIEA在乙腈。从具有附近亚甲基单元的炔酮,可以在相同的反应条件下合成2,5-二取代的呋喃衍生物。
