Abstract
Aryl esters and substituted aryl esters of indole-3-alkanoic acids, such as indole-3-acetic and indole-3-butyric acids, are prepared by a chemical reaction mixture of the acid, a phenol, thiophenol or substituted phenol, a halogenated alkylpyridinium salt, and a tertiary amine in an organic solvent, stirring the mixture for a period of time, and isolating and purifying the product by standard procedures. An aryl amine or substituted aryl amine is substituted for phenol in the reaction mixture when the N-phenyl or N-substituted phenyl indolyl-3-acetamide or butyramide is the desired product. N-phenyl or N-substituted phenyl indolyl-3-acetamides are particularly effective as auxin plant growth regulators and adventitions root initiators.
