The tandem PausonâKhand type reactions of 1,4-enynes tethered by a cyclopropyl group with two molecules of CO proceed smoothly in the presence of [Rh(CO)2Cl]2 under a CO atmosphere to give the corresponding 6-hydroxy-2,3-dihydro-1H-inden-1-one derivatives in moderate yields under mild conditions.
在 CO 气氛下,[Rh(CO)2Cl]2 存在时,1,4-烯炔与两个 CO 分子的串联 PausonâKhand 型反应顺利进行,并在温和条件下以中等产率得到相应的 6-羟基-2,3-二氢-1H-茚-1-酮衍生物。
