Re2O7, which is known primarily as a strong oxidant, was found to be a highly selective Lewis acid catalyst that affects the heteroacylative dimerization of THF at room temperature. This multicomponent reaction, which involves THF, trifluoroacetic anhydride (TFAA), and a carboxylic acid, produces a nonsymmetrical diester, RCO2 (CH2) 4O (CH2) 4OCOCF3, in high yields. The reaction is quite general with respect to the carboxylic acid but is highly ...
