Abstract
Винахід відноситься до органічної хімії. Спосіб синтезу алкіларилсульфіду загальної формули CF3SC6H4X, де Х = Н, CH3 включає взаємодію похідних тіофенолів в апротонному розчиннику з бромтрифторметаном. У якості похідних тіофенолів використовують тіофенол чи тіокрезол у апротонному розчиннику з доданням надлишку по відношенню до тіофенолів піридину чи піколіну, в який послідовно додаються каталізатори метилвіологен та діоксид сірки. Після цього крізь розчин барботується бромтрифторметан у надлишку в 3-5 разів у порівнянні з тіофенолом. Після 3-4 годин барботування у замкненій системі виливали продукт у воду, екстрагували органічним розчинником і відганяли цільовий алкіларилсульфід.The invention relates to organic chemistry. The method of synthesis of alkylarylsulfide of General formula CF3SC6H4X, where X = H, CH3 involves the interaction of thiophenol derivatives in an aprotic solvent with bromotrifluoromethane. Thiophenol or thiocresol in an aprotic solvent is used as thiophenol derivatives with an excess over the thiophenols of pyridine or picoline, to which the catalysts methylviologen and sulfur dioxide are successively added. After that, an excess of 3-5 times more bromotrifluoromethane is bubbled through the solution compared to thiophenol. After 3-4 hours of bubbling in a closed system, the product was poured into water, extracted with an organic solvent and the target alkylaryl sulfide was distilled off.
