Applications

1,3-Bis(trifluoromethyl)benzene undergoes regioselective metalation and subsequent carboxylation at position 2 to give 2,6-bis(trifluoromethyl)benzoic acid. a convenient, selective synthesis of bis[2,4-bis(trifluoromethyl)phenyl]phosphane derivatives with 1,3-bis(trifluoromethyl)benzene as starting material.

Notes

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.

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).
