Method for producing thionocarbamate and dibenzyl disulfide

The invention discloses a method for producing thionocarbamate and dibenzyl disulfide. The method comprises the following steps: carrying out an esterification reaction on alkyl xanthate and benzyl halide to obtain alkyl benzyl xanthate; carrying out an aminolysis reaction on the alkyl benzyl xanthate and fatty amine to obtain a thionocarbamate and benzyl mercaptan mixture; and carrying out an oxidation reaction on the thionocarbamate and benzyl mercaptan mixture and hydrogen peroxide, and carrying out liquid-solid separation to obtain a solid which is the dibenzyl disulfide product and a liquid, and allowing the liquid to stand for oil and water layering in order to obtain an oil phase which is the thionocarbamate product. The dibenzyl disulfide product and thionocarbamate product obtained through the method have high yield and high purity, and the method has the advantages of easiness in separation of the products in the preparation process, environmental protection, high atom economy property, low production cost, and easiness in realization of industrial production.

Identification of new, odor-active thiocarbamates in cress extracts and structure-activity studies on synthesized homologues

New, odorant nitrogen- and sulfur-containing compounds are identified in cress extracts. Cress belongs to the botanical order Brassicales and produces glucosinolates, which are important precursors of nitrogen- and sulfur-containing compounds. Those compo

THE =C=S -> =C=O TRANSFORMATION USING THE SOFT NO(+)-SPECIES

The reaction of NaNO2 in acidic solution with thiocarbonyl compounds has been studied.Secondary- and tertiary thioamides, 1-benzyl-hexahydro-2H-azepine-2-thione, 5-ethyl-5-phenyl thiobarbituric acid, certain thiourea derivatives, 2H-1-benzopyran-2-thione, O,O-diphenyl-thiocarbonic ester, O,S-diphenyl-dithiocarbonic ester, N,N-dimethyl-S-phenyl-dithiocarbamatic ester, N-ethyl-N-phenyl-O-ethyl-thiocarbamatic ester are all converted into the corresponding carbonyl-analogues. 4,4'-Bis(dimethylamino)-thiobenzophenone (Michler's thioketone) gives 3-nitro-4,4'-bis(dimethylamino)-benzophenone at room temperature.At (-10 deg C)-(-5 deg C) the expected oxo compound is obtained as the main product together with 4-(N-nitroso-methylamino)-4'-(dimethylamino)-benzophenone.
