| Abstract: | It is shown that arylthiohydrazides of carboxylic acids undergo cyclization to give both bis (1-methyl-2-indolyl) disulfides and salts of the corresponding 1-methyl-2-aminoindole under the influence of phosphorus halides (POCl3 or PCl3).Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 3, pp. 344–347, March, 1979. |
