A Midas touch! Gold(I)‐catalyzed tandem oxidative ring‐opening/CC bond cleavage reactions of vinylidenecyclopropanes with a variety of secondary amines proceeded smoothly in toluene or 1,1,2,2‐tetrachloroethane (TCE) to give the corresponding amides in moderate to good yields under oxygen atmosphere (see scheme; DCE=1,2‐dichloroethane). The scope and limitations as well as the plausible mechanisms
点石成金!亚乙烯基环丙烷与多种仲胺的金(I)催化串联氧化开环/ CCC键裂解反应在甲苯或1,1,2,2-四氯乙烷(TCE)中顺利进行,得到适度的相应酰胺在氧气气氛下达到良好的收率(参见方案; DCE = 1,2-二氯乙烷)。已经讨论了范围和局限性以及合理的机制。
