Abstract
PURPOSE:To obtain the titled substance useful as an intermediate for medicines, agricultural chemicals, etc., in high purity and yield, by reacting 5,6,7,8- tetrahydro-2-naphthol with thiophosgene in the presence of a dehydrohaloge nating reagent and sulfite, etc. CONSTITUTION:5,6,7,8-Tetrahydro-2-naphthol is reacted with thiophosgene in the presence of a dehydrohalogenating reagent (e.g. alkaline metal hydroxide) and a salt of a sulfur-containing acid as additives in a halogenated hydrocarbon solvent at 0-15 deg.C to afford the titled substance. The additives are selected from sulfites, thiosulfates, dithionites and sulfoxylates and Na, K salts, etc., are used.
