TaCl5 in the synthesis of amides from saturated monobasic carboxylic acids and functionally substituted primary aromatic amines

The reactions of saturated monobasic carboxylic acids with functionally substituted primary aromatic amines (3-amino-2-naphthol, benzo[ d ]thiazol-2-amine, and 4,4′-oxydianiline) with TaCl 5 (0.2 equiv.) were found to be accompanied by the selective formation of carboxylic acid amides of various str...

Description
Summary:The reactions of saturated monobasic carboxylic acids with functionally substituted primary aromatic amines (3-amino-2-naphthol, benzo[ d ]thiazol-2-amine, and 4,4′-oxydianiline) with TaCl 5 (0.2 equiv.) were found to be accompanied by the selective formation of carboxylic acid amides of various structures. A mechanism for the amidation of carboxylic acids in the presence of TaCl 5 was proposed.
