-
Paragraph 0307-0310, (2020/09/15)
A production method in which a mercaptophenol compound is obtained using an industrially preferred sulfur atom introduction reaction, and intermediate compounds of the mercaptophenol compound are provided. A method for producing a mercaptophenol compound in which a phenyl carbamate compound is produced using a phenol compound as a raw material, and then a sulfur atom is regioselectively introduced by a reaction with sulfur monochloride, and a phenyl mercaptocarbamate compound is produced as an intermediate.

A room-temperature Pd(ii)-catalyzed regioselective chlorination reaction has been developed for a facile one-pot synthesis of a broad range of 2-chlorophenols. The reaction demonstrates an excellent regioselectivity and reactivity for C-H chlorination. This reaction represents one of the rare examples of mild C-H functionalization at ambient temperature.

The chlorinating characteristics of the complex (I) of N,N-dimethyldichloromethyleneiminium chloride with chlorine were studied for the case of its reactions with olefins (1-hexene, cyclohexene, tetrachloroethylene), unsaturated alcohols (allyl alcohol), and phenols (phenol, p-cresol).It was found that the ionic chlorination of the olefins by the complex takes place at high rates and with a high degree of selectivity.With the hydroxy compounds there are parallel reactions, in which the chlorinating characteristics of the complex (I) and the reactivity of the N,N-dimethyldichloromethyleneiminium chloride appear.Chlorination of the phenols by the complex (I) takes place at the ortho position, and this leads to the formation of di(o-chloroacyl) carbonates (with the complex and the phenol in a ratio of 1:2) or o-chloroaryl dimethylcarbamates (with the reagents in a ratio of 1:1).
