A method of preparing derivatives of aromatic compounds including the catechol function ##STR1## by replacement of one of the hydroxyls by mercaptan ##STR2## Cathechol or a multi-ring compound (naphthyl-, anthryl-, phenanthryl-, etc.) containing the catechol function is first reacted with thiophosgene to produce the corresponding dioxole-2-thione ##STR3## The thione is ammonolyzed to the corresponding hydroxy N,N-disubstituted thionocarbamate ##STR4## The thionocarbamate is acetylated to ##STR5## and heated to rearrange the compound to the corresponding thiolcarbamate ##STR6## Further heating produces the corresponding oxathiol-2-one ##STR7## which can be hydrolyzed to the corresponding mercaptan ##STR8##
一种制备含有间苯二酚结构的芳香化合物衍生物的方法,包括通过将其中一个羟基替换为巯基来制备。首先将间苯二酚或含有间苯二酚结构的多环化合物(萘基、蒽基、菲基等)与硫代氯酰反应,得到相应的二噁烯-2-硫酮。然后将硫酮氨解,得到相应的羟基N,N-二取代硫代氨基甲酸酯。接着对硫代氨基甲酸酯进行乙酰化,得到相应的化合物,并加热使其重排成相应的硫酰氨基甲酸酯。进一步加热得到相应的噁硫酮-2-酮,可水解得到相应的巯基。
