Abstract
3-Thioformylindole and its previously unknown 2-methyl-, 2 -phenyl-, and 1-ethyl substituted derivatives have been synthesized by the thiolysis of the corresponding indolylmethylenimmonium perchlorates. The thioaldehydes containing no substitutdt at the nitrogen atom were isolated as crystalline solvates with DMSO and DMF. Monitoring of 3-thioformylindole formation was effected by polarography and spectrophotometry.
