Procedure

Aluminum tris-triflate (CF3SO3)3Al is prepared by placing a premeasured amount of anhydrous aluminum trichloride (tribromide) in a well dried three necked flask equipped with a magnetic stirrer, a pressure equalizing dropping funnel and dry nitrogen inlet. The flask is cooled and 3 equivalents of triflic acid are slowly added from the dropping funnel with efficient stirring whereby HCl (HBr) slowly evolves. The temperature was slowly raised until completion of the reaction. The flask is then evacuated in vacuum to remove any HX and residual triflic acid giving aluminum triflate as a slightly off colored solid.
