3-benzothiazole reacts with anilines to form the corresponding trifluoromethyl-substituted alcohols. The reaction regioselectivity (ortho/para) was shown to depend strongly on the structure of the aniline. meta-Substituted anilines tend to form the corresponding ortho-substituted products, in contrary to the previous literature data. anilines- Friedel-Crafts alkylation-ortho/para-substitution - trifluoromethyl

solvent-free and catalyst-free approach for the synthesis of structurally diverse gem-difluorinated and polyfluoroarylated derivatives with readily available nucleophilic and electrophilic fluorine-containingreaction partners, difluoroenoxysilane and pentafluorobenzaldehyde, is described. This neat protocol is induced by the direct hydrogen-bond interactions between fluorinated and non-fluorinated reactants
