ABSTRACT:
New 1,1,1-triaryl-2,2,2-trifluoroethanes in which the aryl radicals carry one or more substitutents have been prepared by condensation of trifluoroacetophenones with substituted phenyl compounds in the presence of catalytic quantities of trifluoromethylsulfonic acid. The reaction can be carried out under reflux in toluene or, for strikingly better results in certain cases, reactants are simply stirred at room temperature for about 24 to 48 hours.
