  氢化钌催化α，β-不饱和醛与伯醇的交叉偶联反应合成2-羟基甲基酮

  摘要：

  使用RuHCl（CO）（PPh 3）3作为催化剂，可以实现α，β-不饱和醛与伯醇的交叉偶联反应，生成2-羟甲基酮。这种原子经济反应很可能是通过α，β-不饱和醛的加氢钌化反应进行的，然后是烯醇与醛的醛醇缩合反应，生成α-甲酰化的酮，然后与伯醇进行转移氢化反应，生成α-羟甲基酮。 。还原步骤可产生醛，参与下一催化循环。

• Lanthanide Trifluoromethanesulfonates as Stable Lewis Acids in Aqueous Media. Yb(OTf)₃Catalyzed Hydroxymethylation Reaction of Silyl Enol Ethers with Commercial Formaldehyde Solution
  作者：Shu Kobayashi

  DOI：10.1246/cl.1991.2187

  日期：1991.12

  Silyl enol ethers smoothly react with commercial formaldehyde solution to give the corresponding hydroxymethylated adducts in high yields by the promotion of a catalytic amount of ytterbium(III) triflate (Yb(OTf)3), which is a stable Lewis acid in aqueous media. Other lanthanide triflates are also found to be effective.

• Lanthanide Triflates as Water-Tolerant Lewis Acids. Activation of Commercial Formaldehyde Solution and Use in the Aldol Reaction of Silyl Enol Ethers with Aldehydes in Aqueous Media

  Lanthanide trifluoromethanesulfonates (triflates), especially ytterbium triflate (Yb(OTf)(3)), were found to be stable Lewis acids in water. In the presence of a catalytic amount of lanthanide triflate, formaldehyde in water solution (commercial formaldehyde solution) was activated and the hydroxymethylation reaction of silyl enol ethers proceeded smoothly. Lanthanide triflates were also quite effective in the aldol reaction of silyl enol ethers with aldehydes in aqueous media, and water-soluble aldehydes such as acetaldehyde, acrolein, and chloroacetaldehyde could be employed for direct use. Moreover, in all these reactions, lanthanide triflates were quantitatively recovered after the reactions were completed and could be reused.
