An efficient strategy for the para-selective borylation of aromatic esters is described. For achieving high para-selectivity, a new catalytic system has been developed modifying the core structure of the bipyridine. It has been proposed that the L-shaped ligand is essential to recognize the functionality of the oxygen atom of the ester carbonyl group via noncovalent interaction, which provides an unprecedented
描述了一种用于芳族酯的对位选择性硼化的有效策略。为了获得高的对位选择性,已经开发了一种新的催化体系,该体系改变了联吡啶的核心结构。有人提出,L型配体对于通过非共价相互作用识别酯羰基的氧原子的功能至关重要,这为超选择性C–H活化/硼化提供了空前的控制因素。
