Gold-catalyzed nucleophilic substitution of propargylic alcohols with various nucleophiles (allylsilane, electron-rich aromatics, alcohols, thiols, hydrides, 1,3-dicarbonyl derivatives, sulfonamides) is described under very mild conditions (room temperature in dichloromethane). Preliminary mechanistic investigations suggest a mechanism through a carbocation intermediate. Nucleophilic substitutions on allylic
在非常温和的条件下(室温于二氯甲烷中)描述了金催化的炔丙醇被各种亲核试剂(烯丙基硅烷,富电子芳族化合物,醇,硫醇,氢化物,1,3-二羰基衍生物,磺酰胺)取代。初步的机理研究表明,是通过碳正离子中间体形成的。还描述了烯丙基和苄基醇上的亲核取代。
