METHOD FOR PREPARING 2,3,4,5-TETRAALKYLTHIOPHENOLS Russian patent published in 2007 - IPC C07D333/10 C07D333/08 

Abstract RU 2310650 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of 2,3,4,5-tetraalkylthiophenols. Method involves interaction of disubstituted acelylenes with n-BuMgCl and sulfur monochloride (S2Cl2) in the presence of zirconacene dichloride as a catalyst, in argon atmosphere, at room temperature in diethyl ether medium for 6-10 h. Proposed method provides preparing the end product with the yield 40-54% by simplified technology and with using easily available and nontoxic raw. Synthesized compounds can be used in food processing industry, as biologically active compounds, dyes, addition agents to oils and hydraulic liquids.

EFFECT: improved method of synthesis.
