发明名称 METHOD FOR PREPARING 2,3,4,5-TETRAALKYLTHIOPHENES
摘要 FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to a method for synthesis of 2,3,4,5-tetraalkylthiophenes. Method involves interaction of disubstituted acetylenes with R'-AlCl2 and SOCl2 in the presence of metallic Mg and zirconacene dichloride as a catalyst in argon atmosphere in tetrahydrofuran medium for 11-15 h. Proposed method shows the simplified technology and uses easily available and nontoxic raw and provides preparing the end product with the yield about 47-54%. Synthesized compounds can be used in food industry, as biologically active compounds, dyes, addition agents to oils and hydraulic liquids. ^ EFFECT: improved method of synthesis, valuable properties of compounds. ^ 1 tbl, 10 ex
