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.
