Chemical Properties
Cerium(IV) Trifluoromethanesulfonate (ceric triflate) is a oxidizing agent for benzyl alcohols and toluenes; yellow powder or solid; sol water, THF, DME, dioxane; insol dichloromethane, hexane, benzene.
Uses
Cerium(IV) trifluoromethanesulfonate, is used as a strong oxidizing agent, in the oxidation of benzyl alcohols and alkylbenzenes to aryl aldehydes and aryl ketones respectively. It can also be used as a catalyst for high-yield deprotection of tert-butyldimethylsilyl ethers
Preparation
By the reaction of trifluoromethanesulfonic acid with freshly prepared
cerium(IV) carbonate
[1]. Cerium(IV) Trifluoromethanesulfonate can be prepared in situ by the electrochemical oxidation of
Ce(OTf)3 in aqueous trifluoromethanesulfonic acid
[2].
storage
Cerium(IV) trifluoromethanesulfonate is extremely hygroscopic and should be
stored under strict absence of moisture. This reagent should be handled in a fume hood.
