Ethyl 3-chloro-3-(3, 4-dichlorophenylthio)propanoate (8) reacted with electron-rich arenes in the presence of titanium tetrachloride to give the Friedel-Crafts products 10a-13a. Reactions of 8 with 1-trimethylsilylalkynes 14a-d were effected with aluminum chloride to afford the substitution products 15a-d. Some chemical transformations of the products are also described.
乙基3-氯-3-(3,4-二氯苯硫)丙酸酯(8)在四氯化钛存在下与富电子的芳烃反应,生成Friedel-Crafts产物10a-13a。8与1-三甲基硅基炔烃14a-d的反应在氯化铝的作用下进行,得到了取代产物15a-d。文中还描述了一些产物的化学转化。
