Description

General description

Bis(trifluoromethylsulfonyl)methylbenzene (aryl bistriflylmethane) is a strong Brønsted acid with pKa values of 12.5 in CD₃CO₂D, 7.83 in CH₃CN, and 2.0 in DMSO.

Application

Aryl bistriflylmethane can be used as a catalyst for the polymerization of epoxides. It can also be used in the protonation of organometallic species to promote a variety of processes such as reductive elimination, trimerization of alkynes, olefin isomerization, and hydroformylation reactions.
