ABSTRACT:
Aryl esters and thioesters of indole-3-alkanoic acids, such as indole-3-acetaic acid and indole-3-butyric acid, are prepared by chemical reaction of the acid with a phenol, substituted phenol, or thiophenol in a tertiary amine solvent. A phosphorus or sulfur halide in a suitable solvent is added dropwise to the cold amine solution. The reaction produced is separated and purified by standard methods. Phenyl-indole-3-thiolobutyrate as well as other aryl esters of indole-3-alkanoic acids is effective as an auxin plant growth regulator and adventitious root initiator.
