The Grignard reaction of the methyl ethers (I and III) of 3-bromotropolone and those (II and IV) of 3-chlorotropolone with methylmagnesium iodide or phenylmagnesium bromide were investigated. When I or II was allowed to react with methylmagnesium iodide, 2-methoxyphenyldimethylcarbinol (V) and 2-methoxy-6-isopropylphenol (VI) were obtained. The reaction of I or II with phenylmagnesium bromide afforded
研究了3-溴托罗酮的甲醚(I和III)和3-氯托酚酮的甲醚(II和IV)与甲基碘化镁或苯基溴化镁的格氏反应。当I或II与碘化甲基镁反应时,得到2-甲氧基苯基二甲基甲醇(V)和2-甲氧基-6-异丙基苯酚(VI)。I 或 II 与溴化苯基镁反应得到 2-苯基-7-卤代酮(XIII 或 XVII),伴随有 2-卤代二苯甲酮(XV 或 XVIII)和三苯基甲醇衍生物(XIV)。使用溴化苯基镁进行 III 或 IV 的格氏反应得到 2-苯基-3-卤代酮(XVI 或 XIX)。讨论了这些产品形成的机理途径。
