- Metallation with n-BuLi in diethyl ether is unselective, giving, on quenching with CO2, a mixture of 2,4- and 2,6-bis(trifluoromethyl)benzoic acids: J. Organomet. Chem., 67, 321 (1974). The superbasic n-BuLi/KO-t-Bu combination leads to almost exclusive 2-metallation, allowing the 2,6-bis(trifluoromethyl) acid to be isolated in 78% yield. In contrast, a combination of sec-BuLi and N,N,N',N',N'-pentamethyldiethylenetriamine leads to the 2,4-bis(trifluoromethyl) acid as the main product: Synlett, 747 (1990).
