Catalytic aldol reactions of several aldehydes with trimethylsilyl enol ethers are effectively performed by combined use of diphenyltin sulfide (Ph2Sn=S) and silver perchlorate (AgClO4) or Lawesson’s reagent (2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide) and silver perchlorate under mild conditions.
通过结合使用二苯基硫化锡 (Ph2Sn=S) 和高氯酸银 (AgClO4) 或 Lawesson 试剂(2,4-双(4-甲氧基苯基)-1,3-二硫杂),可以有效地进行几种醛与三甲基甲硅烷基烯醇醚的催化羟醛反应-2,4-diphosphetane-2,4-disulfide) 和高氯酸银在温和条件下。
