palladium-catalyzed cross-coupling of aryl fluorosulfonates and aryl boronic acids. These reactions occur in good to excellent yields under mild conditions with excellent functional group compatibility employing either Pd(OAc)2 and inexpensive PPh3 or the inexpensive and readily available NiCl2(PCy3)2. Importantly, the in situ conversion of phenol derivatives to the corresponding aryl fluorosulfonate by reaction
本文报道了芳基氟磺酸盐和芳基硼酸的镍和钯催化的交叉偶联的实例。这些反应在温和条件下以良好的收率产生,并具有优异的官能团相容性,采用Pd(OAc)2和廉价的PPh 3或廉价且易于获得的NiCl 2(PCy 3)2。重要地,描述了通过与硫酰氟和碱反应并随后在单个罐中交叉偶联形成联芳基而将苯酚衍生物原位转化为相应的氟代磺酸芳基酯。这些方法学中报道的廉价的硫酰氟和有效的催化剂的结合将使制药和农业化学过程中苯酚的经济Suzuki偶联成为可能。
