METHOD OF IDENTIFYING AN AQUEOUS SYSTEM LEWIS ACID CATALYST FOR THE ALDOL REACTION. |
| 摘要 |
<p>A reaction method by a novel Lewis acid catalyst stable in water for organic synthesis by using a metal compound stable in water and functioning as a Lewis acid catalyst and using water as apart or all of a solvent, the metal ion of the metal compound having a hydrolysis constant (pKh) of : 4.3 ≤ pKh ≤ 10.1 and a water exchange rate constant (WERC) of 3.2 x 10<6>M<-1>sec<-1> or more.</p> |
