Synthesis and Derivatives

Hydroquinone [123-31 -9] resorcinol [108-46-3] and catechol [120-80-9] (or pyrocatechol) are represented by structures (1), (2), and (3), respectively. This article reviews their syntheses and derivatives, production and use, and toxicology. 

Thiaphosphetane chemistry, long neglected, is being investigated. Both the 1,2- and the 1,3-thiaphosphetanes have been synthesized and derived. The structure 287 was prepared by Soviet chemists " in 1969 and 1970. Schmidt and Hamblin have produced a variety of ammonium salts of the phosphathietanes that they have patented as effective lubricants, (see 23 in Section II).
