would be difficult to produce in an efficient manner. This method relies on a palladium-catalyzed cross-coupling reaction of various brominated PAHs with cyclohexanone to yield α-arylated ketones, which are converted to regiospecific vinyl triflates and cyclized by a palladium-catalyzed intramolecular arene–vinyl triflate coupling to produce PAHs with incorporated saturated rings or “tetrahydroindeno-annulated”
已经开发了一种使多环芳族烃(PAH)环合的新的有效三步法,该方法可提供带有饱和环的PAH,而在目前的化学方法下,饱和环很难以有效的方式生产。此方法依赖于各种溴化PAH与环己酮的钯催化交叉偶联反应,以生成α-芳基酮,然后将其转化为区域特异性的乙烯基三氟甲磺酸酯,并通过钯催化的分子内芳烃-乙烯基三氟甲磺酸酯偶合反应,生成结合了PAH的PAH。饱和环或“四氢茚基环化” PAH。
