Chemistry of Heterocyclic Compounds Aims and scope

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).
