Usage
Core Reagents for Organic Synthesis: Potent triflating agents that convert alcohols, phenols, and amides into triflates or triflamides, generating highly active leaving groups for use in coupling reactions such as Suzuki and Heck couplings.
Pharmaceutical Intermediate Synthesis: Preparation of intermediates for antiviral and antitumor drugs; catalysts for glycosylation reactions; synthesis of complex carbohydrates.
Catalysis: Super-strong Lewis acids catalyzing Friedel-Crafts reactions, rearrangements, polymerizations, and dehydration reactions.
New Materials: Preparation of triflate salts, ionic liquids, and conductive polymers; synthesis of electronic chemicals.
Fine Chemicals: Dehydrating agents used in the preparation of nitriles, lactones, acid anhydrides, and more.
