Zinc trifluoromethanesulfonate (Cat No.:R074481) is a Lewis acid catalyst composed of a zinc ion coordinated by two trifluoromethanesulfonate (triflate, OTf⁻) anions. It is widely used in organic synthesis for promoting a variety of reactions including Friedel–Crafts acylations, Diels–Alder cycloadditions, and glycosylation reactions. Its non-coordinating triflate ligands enhance catalytic activity and solubility in organic solvents. Compared to traditional zinc salts, this compound offers greater efficiency and milder reaction conditions. It is valued in medicinal and materials chemistry for its role in forming carbon–carbon and carbon–heteroatom bonds with high selectivity.
