Product Information

• Name: 2,2,2-Trifluoroethyl 4-methylbenzenesulfonate
• Brand: Biosynth
• Description: 2,2,2-Trifluoroethyl 4-methylbenzenesulfonate (TFMBES) is a nucleophile that is used in cross-coupling reactions. It can be prepared by the reaction of butyllithium with 2,2,2-trifluoroethanol and then reacting it with methyl benzenesulfonyl chloride. TFMBES reacts with palladium dichloride to form a palladium-carbanion complex that then reacts with an organic electrophile to form the desired product. TFMBES is also used as a precursor in the preparation of trialkylboranes, which are precursors for dehydrogenation reactions.
