subsequent trapping of the resulting quinone methide with a variety of oxygen and nitrogen nucleophiles was achieved. Both β-β and β-O coupling isomers can be synthesized via either C-C coupling and two nucleophilic additions of one water molecule (β-β isomer) or C-O coupling followed by one nucleophilic addition of a water molecule (β-O isomer), respectively. Selectivity between these outcomes was achieved
实现了对烯基
苯酚的氧化均偶联和随后用各种氧和氮亲核试剂捕获所得的醌甲基化物。β-β和β-O偶联异构体都可以通过CC偶联和两个亲核加成一个
水分子(β-β异构体)或CO偶联,然后亲核加成一个
水分子(β-O异构体)来合成,分别。这些结果之间的选择性是通过对机制的理解来实现的。具体而言,基于催化剂电子学,溶剂极性和浓度建立了偶联选择性的定性预测模型。
