Thiel, W. published the artcileDithiocarboxylic acids, dithiocarboxylic esters, or thiocarboxylic amides by reaction of methylene-active chloromethyl compounds with sulfur, SDS of cas: 4760-35-4, the publication is Journal fuer Praktische Chemie (Leipzig) (1989), 331(2), 243-62, database is CAplus.
With a mixture of S and amine in DMF at room temperature halomethyl compounds can be oxidized to give thiocarboxylic acids and their derivatives The reaction was studied in detail especially with chloroacetic derivatives or chloromethyl heterocycles formally derived from chloroacetic acid. The resulting thiooxalic acid derivatives represent activated acids and very useful C2-synthons, especially for the synthesis of heterocycles. Oxidation in the presence of Et3N leads to dithiocarboxylates which can be alkylated to dithioesters in high yields. As a rule, with different primary and secondary amines instead of tertiary amines these dithiocarboxylates or dithiocarboxylic esters can be transformed already at low temperatures to thioamides.
Journal fuer Praktische Chemie (Leipzig) published new progress about 4760-35-4. 4760-35-4 belongs to imidazoles-derivatives, auxiliary class Chloride,Benzimidazole, name is 2-(Chloromethyl)-1-methyl-1H-benzo[d]imidazole, and the molecular formula is C16H12O, SDS of cas: 4760-35-4.
