摘要：
The reaction of alkyl- and aryl-substituted carboxylic acids with primary and secondary amines under the action of 0.2 equiv. TaCl5 leads to selective formation of carboxylic acid amides of various structures. TaCl5-catalyzed formation of amides was demonstrated to proceed equally selectively both in toluene and methylene chloride, hexane, diethyl ether and 1,4-dioxane solutions.
