报道了氰基二硫代甲酸钠1和顺式-1,2-二氰乙烯-1,2-二硫醇2二钠盐的新合成方法。关键的一步是从取代的乙腈4开始与单质硫进行亲核硫基化。该方法可作为制备上述化合物的不含氰化物和二硫化碳的替代方法。
A new synthesis of sodium cyanodithioformate 1 and the disodium salt of cis-1,2-dicyanoethylene-1,2-dithiol 2 is reported. The key step involves a nucleophilic thiolation with elemental sulfur starting from a substituted acetonitrile 4. This method may serve as a cyanide-and carbondisulfide-free alternative in the preparation of the title compounds.
