Technical Note:
1. Microencapsulated Scandium triflate is a useful Lewis acid catalyst which can be applied to various synthetic procedures such as the aldol, Michael, alkylation, Friedel-Crafts acylation, Mannich and Strecher type reactions. The encapsulated Sc(SO3CF3)3 has a higher activity than the free monomer, can easily be separated from the reaction mixture, and is reusable.
