Title:
PREPARATION METHOD FOR CHEMICAL INTERMEDIATE 2,2'-DITHIOCARBAMIDES COMPOUND
Document Type and Number:
WIPO Patent Application WO/2020/114376
Kind Code:
A1
Abstract:
The present invention provides a preparation method for a chemical intermediate 2,2'-dithiocarbamides compound. A 2-position substituted benzamides compound is reacted with a sulfur reagent in an aprotic solvent of a high boiling point under the combined action of metal salt and a ligand to generate the 2,2'-dithiocarbamides compound. The 2,2'-dithiocarbamides compound of the present invention is an important chemical intermediate. The synthesis route is simple, and the pollution of three wastes to the environment is reduced while lowering the cost.
