The present invention relates to cyclic 5-membered ring dithiocarbonate compounds of the general formula
wherein, in the formula, R1, R2, and R3 are the same or different, each of which denotes hydrogen or a C1 to C4 straight-chain or branched alkyl. The invention further relates to a process for producing these compounds and a variety of products obtainable by reacting the title compounds.
Thiolysis of a variety of 1,2-epoxides in water at 30degreesC and pH 7.0 is strongly accelerated by ZnCl(2) (10 mol %) except when amino- and carboxythiophenol are used. The aqueous medium and the catalyst were recovered and reused in various runs without affecting the efficiency of the process.
