Abstract

The reaction of perhaloethyl isocyanates with o-mercaptophenol and o-dimercaptobenzene gave 4-trihalomethyl-2-oxobenz-1,5,3-oxathiazepines and 2-oxo-4-trichloromethylbenz-1,5,3-dithiazepine, which at 100–110°C undergo contraction of the heteroring and are converted to the corresponding 2-trihalomethyl-2-isocyanato-1,3-oxathiolanes and a dithiolane.
