PROBLEM TO BE SOLVED: To execute an organic synthetic reaction in a water medium by a method wherein a surface active function is provided by allowing a hydrophobic atomic group and a hydrophilic atomic group are allowed to exist in a molecule to have a surface-active function, and a specific surface active Lewis acid catalyst having a Lewis acidity in a part of the hydrophilic atomic group is obtained. SOLUTION: A surface active Lewis acid catalyst represented by M<n+> (R<1> X<-> )k (R<2> X<-> )l (Y<-> )m is imparted with a surface-active function by allowing a hydrophobic atomic group and a hydrophilic atomic group to exist in a molecule, and a Lewis acidity is equipped to a part of the hydrophilic atomic group. Wherein, in the formula, (k+l+m)=n is provided, (n) indicates a number of 1 or over, (k), (l) and (m) each indicate a number of 0 to 3, M indicates a kind of a transition metal element, X indicates a conjugated salt group of an organic acid group, R<1> indicates a hydrocarbon group which may have a 8-30C functional group, R<2> indicates a hydrocarbon group which may have a 1-12C functional group, and Y respectively indicates an inorganic anion. |
