Abstract
Reactions of haloarenes with urotropine in CF3COOH at elevated temperatures and high pressures give the corresponding aromatic aldehydes and/orN-(haloarylmethyl)trifluoroacetamides. The yeilds of the products and their ratio depend on electronic properties of substituents in the aromatic ring. The reaction carried out in a mixture of CF3COOH and (CF3CO)2O affords only amides.
