using Ru3(CO)12 as the catalyst and α-oxocarboxylic acids as the acylation source, featured broad substrate scope, good functional group tolerance, and high regioselectivity. Mechanistic studies demonstrated that a radical process and an 18e-octahedral ruthenium species were involved in this reaction. The present work provides a new strategy for the regioselective meta-acylation reactions and will
通过钌催化的邻位金属化策略,可以建立多种芳烃的直接脱羧间选择性C–H酰化反应。该方法以Ru 3(CO)12为催化剂,α-氧代羧酸为酰化源,具有较宽的底物范围,良好的官能团耐受性和较高的区域选择性。机理研究表明,该反应涉及自由基过程和18e-八面体钌物种。目前的工作为区域选择性间酰化反应提供了一种新的策略,并将成为药物和材料科学发展的有力工具。
