说明

一般描述

Calcium trifluoromethanesulfonate, also known as calcium triflate [Ca(OTf)2], is widely employed as a Lewis acid catalyst in organic synthesis. It facilitates a range of reactions, including the aldol reaction, Michael additions, and ring-opening reactions of epoxides. In addition, it is also used as a reagent for the preparation of trifluoromethanesulfonate esters, which can be used as leaving groups in a range of organic transformations.
 

应用

Calcium trifluoromethanesulfonate can be used as a catalyst to synthesize β-amino alcohols via aminolysis of epoxides. It is also used in the one-pot conversion of aldehydes to their corresponding nitrile compounds.
