Sc(OTf) 3 is a new type of a Lewis acid that is different from using a small amount of Sc(OTf) 3 in both organic and aqueous solvents. In addition, Sc(OTf) 3 can be recovered typical Lewis acids such as AlCl 3 , BF 3 , SnCl 4 , etc. While most Lewis acids are decomposed or deactivated in the presenc

โฆ Synopsis
Numerous Lewis acids are known that effectively catalyze Friedel-Crafts and related reactions, however a shortcoming of most reagents is associated with quenching the reaction; catalysts cannot be reused, causing problems with waste disposal. Like many rare earth salts, copper(II) triflate has the advantage of being recyclable from aqueous solutions after
