Tetraflic acid offers ample acidity for various organic reactions that require high acidity. Its gallium(III) salt is an efficientcatalyst under mild condtions for synthetic transformations such as the ketonic Streckerreaction for the synthesis of fluorinated α-aminonitriles and condensation–cyclzation reactionsusing suitable fluoro ketones and 1,2-disubstituted benzenes for the direct preparation
