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.
新的1,1,1-三芳基-2,2,2-
三氟乙烷已经制备出来,其中芳基基团携带一个或多个取代基,通过在
三氟甲磺酸催化下,三
氟乙酰苯酮与取代苯基化合物缩合反应而成。该反应可以在
甲苯中回流进行,或者在某些情况下,反应物在室温下简单搅拌约24至48小时可获得显着更好的结果。
