METHOD OF DETERMINING A WATER SYSTEM CONTAINING A LIQUID ACID CATALYSATOR FOR ALDOL REACTIONS

摘要

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 106M-1sec-1 or more.
