Abstract
An acid-catalyzed reaction of substituted 5-chloro-2-methylbenzothiazoles with 3,4,5,6-tetrachloro-1,2-benzoquinone leads to 5,6,7-trichloro-2-(5-chlorobenzothiazol-2-yl)-1,3-tropolone and 4,5,6,7-tetrachloro-2-(5-chlorobenzothiazol-2-yl)-1,3-tropolone. Molecular structure of 4,5,6,7-tetrachloro-2-(5-chlorobenzothiazol-2-yl)-1,3-tropolone was established by X-ray crystallography.
