Acylation of hetarylacetonitriles and hetarylylideneacetonitriles with acetylmercaptoacetyl chloride gave 3-cyano-3-hetarylylidene-2-oxopropyl ethanethioates. 2-Amino-3-hetaryl-4(5H)oxothio-phenes or 2-hetarylylidene-3-oxo-4-sulfanylbutanenitriles were obtained on treating them with bases. Acylation of hetarylacetonitriles with 3-acetylmercaptopropionyl chloride gave 4-cyano-4-hetaryl-ylidene-3-oxobutyl ethanethioates, deacetylation of which gave 2-hetarylylidene-3-oxo-5-sulfanyl-pentanenitriles.
