Popis

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Green Chemistry. This catalyst excels in propargylation of carbonyl compounds and silicon-based nucleophile activation. Its strong Lewis acidity with moisture tolerance makes it superior to traditional Lewis acids for diverse transformations. Click here for more information.

Application

• Silver trifluoromethanesulfonate (AgOTf ) is a reactive triflating agent, which converts alkyl, acyl and sulfonyl halides to corresponding triflate species.
• It is a highly suitable electrophile to initiate acetylenic oxy-Cope rearrangement of substituted 5-hexen-1-yn-3-ols to synthesize corresponding α,δ-diethylenic aldehydes.
• It can also be used in the diastereoselective cyclization of amino ketenes where the diastereoselectivity depends on Ag(I) concentration.
