A nontoxic FeCl3 catalyzed intramolecular oxidative coupling reaction was developed for mild synthesis of a series of phenanthrenes with different substituents. The method involves cross dehydrogenative coupling of a variety of 1,2‐diarylethylene derivatives with di‐tert‐butylperoxide (DTBP) as a sole oxidant at room temperature in CH2Cl2/TFA (9:1 V/V) to yield phenanthrenes in good to excellent yields
开发了一种无毒的FeCl 3催化的分子内氧化偶联反应,用于轻度合成一系列具有不同取代基的菲。该方法涉及在室温下在CH 2 Cl 2 / TFA(9:1 V / V)中将多种1,2-二芳基乙烯衍生物与二叔丁基过氧化物(DTBP)作为唯一氧化剂进行交叉脱氢偶联以生成菲产量高到极好。
