An oxidative procedure for the electrophilic iodination of phenols was developed by using iodosylbenzene as a nontoxic iodine(III)-based oxidant and ammonium iodide as a cheap iodine atom source. A totally controlled monoiodination was achieved by buffering the reaction medium with K3PO4. This protocol proceeds with short reaction times, at mild temperatures, in an open flask, and generally with high
通过使用碘基苯作为无毒的碘(III)基氧化剂和碘化铵作为廉价的碘原子源,开发了一种用于亲电子碘化苯酚的氧化方法。通过用K 3 PO 4缓冲反应介质来实现完全受控的单碘化。在温和的温度下,在开放的烧瓶中,该方案以较短的反应时间进行,并且通常收率很高。用富电子和贫电子的酚以及杂环探索了革兰氏反应以及该方案的范围。量子化学计算显示,PhII(OH)·NH 3是最可能的碘化活性物质,呈反应性“ I +synthon。鉴于碘代芳烃部分的相关性,我们在本文中提出了实用,有效和简单的方法,其具有允许进入碘代芳烃核心单元的宽泛的官能团范围。
