| Abstract: | An IR study of thiocarboxylic acid N-(1-arenesulfonamido-2-phenyl-2,2-dichloroethyl- and -2,2,2-trichloroethyl)amides revealed intramolecular hydrogen bonds whose formation is accompanied by electron density delocalization and stabilization of conformations with quasiaromatic rings. Formation of chelate species was confirmed by AM1 calculations. |
