Article abstract of DOI:10.1007/BF00505844

5-Methylthio-2-oxo-2,3-dihydro-1H-imidazo<1,2-c>thiazolium salts readily react with 3-ethylrhodanine, p-dimethylaminobenzaldehyde, and 3-ethyl-2-methylbenzothiazolium tosylate with the formation of polymethine dyes, including dyes with a mesoionic structure.Reaction with acetic anhydride has given acetyl-substituted imidazothiazolium 2-oxides.
