A dream combination for catalysis: highly reactive and recyclable scandium(III) triflate-catalyzed cyanosilylations of carbonyl compounds in an ionic liquid

摘要

The catalytic activity of lanthanide triflates, particularly scandium triflate, increased dramatically in [bmim][SbF6], allowing the cyanosilylation of a variety of aldehydes and ketones with a turnover frequency up to 48000 mol h~(-1) and a total turnover number of 100000.
