The Brønsted aids: The first dehydrogenative arylation of β‐keto esters with arenes under ambient aerobic conditions is described (see scheme). Under a PdII/Brønsted acid co‐catalytic system, regioselective arylations with alkoxylated arenes and phenols were achieved in good yields, even in gram‐scale conditions.
布朗斯台德助剂:描述了在环境好氧条件下,β-酮酯与芳烃的第一次脱氢芳基化反应(参见方案)。在Pd II /布朗斯台德酸共催化体系下,即使在克级条件下,也能以良好的收率实现烷氧基化的芳烃和苯酚的区域选择性芳基化。
