The first iron-catalyzed esterification of the primary benzylic C–H bonds with carboxylic acids using di-tert-butyl peroxide as an oxidant is achieved by novel ionic iron(III) complexes containing an imidazolinium cation. The use of well-defined, air-stable, and available iron(III) complex in a 5 mol % loading and readily available starting materials with a broad generality and outstanding sterically
新型的含咪唑啉阳离子的离子型铁(III)络合物实现了使用过氧化二叔丁基作为氧化剂对伯苄基C–H键与羧酸进行的首次铁催化酯化反应。使用定义明确,空气稳定且可用的铁(III)配合物(负载量为5 mol%)以及易于获得的起始材料(具有广泛的通用性和出色的空间位阻性),使该方法成为常规方法中其他方法的有用替代方法用于合成苄基酯。
