2-acetylenic phenyl sulfides into 1-methoxy-2-acetylenic phenyl sulfides. Oxidation with chromic acid gave 2-acetylenic carboxylic acids. Oxidation of 2-acetylenic phenyl sulfides with Oxone® and hydrogen peroxide in acetic acid gave the corresponding sulfoxides and sulfones respectively. Diethylamine addition to the triple bond produced enamines which were hydrolyzed with aqueous hydrochloric acid to the corresponding
摘要 用
磺酰氯在 1-位单
氯化,然后
甲醇分解将 2-炔基苯
硫醚转化为 1-甲氧基-2-炔基苯
硫醚。用
铬酸氧化得到2-炔
羧酸。用 Oxone® 和
过氧化氢在
乙酸中氧化 2-炔属苯
硫醚,分别得到相应的亚砜和砜。
二乙胺加成到三键产生烯胺,用
盐酸水溶液将其
水解成相应的 1-亚磺酰基和 1-磺酰基-2-酮。
