A metal-free, oxidative coupling of phenols with various nucleophiles, including arenes, 1,3-diketones and other phenols, is reported. Cross-coupling is mediated by a sulfoxide which inverts the reactivity of the phenol partner. Crucially, the process shows high selectivity for cross-versus homo-coupling and allows efficient access to a variety of aromatic scaffolds including biaryls, benzofurans and
据报道,苯酚与各种亲核试剂(包括芳烃,1,3-二酮和其他酚)的无金属氧化偶联反应。交叉偶联是由亚砜介导的,该亚砜会使苯酚配体的反应性发生转化。至关重要的是,该方法示出了对于交高选择性与同型耦合,并允许各种芳族的支架,包括联芳基,苯并呋喃并,通过迭代过程,芳族低聚物的有效访问。
