The application of combination catalysis in enantioselective trifluoromethylation reactions is illustrated. Four ground-breaking studies have described the efficient catalytic enantioselective nucleophilic trifluoromethylation of ketones and azomethine imines in the presence of the combination of a Cinchona alkaloid-derived ammonium salt and different nucleophilic initiators, whereas the highly enantioselective electrophilic and radical trifluoromethylation of aldehydes could be achieved via the combination of chiral organocatalysts and metal salts.
