It was established that indole and 2-methylindole are converted in soil to stable compounds, which were isolated and identified by means of mass spectrometry (low-and high-resolution), IR, UV, and PMR spectroscopy, and by comparison with model samples. Under the influence of peroxide compounds in the soil, indole is converted to 2,2-di(3-indolyl)indoxyl and very small amounts of indoxylrot, indirubin, and indigo. Similarly, 2-methylindole is converted in soil to 2-methyl-2-(2-methyl-3-indolyl)-3-oxoindoline.
