synthetic chemistry. The use of attractive noncovalent interactions between the catalyst and substrate is emerging as a versatile approach to address site-selectivity challenges. Herein, we designed and synthesized a series of palladacycles, to control meta-selective Suzuki coupling of 3,4-dichlorophenol and 3,4-dichlorobenzyl alcohol. Noncovalent interactions directed zwitterionic aqua palladacycles
具有多个反应位点的底物的位点选择性反应一直是当前合成化学的焦点。催化剂和底物之间有吸引力的非共价相互作用的使用正在成为解决位点选择性挑战的通用方法。在此,我们设计并合成了一系列环钯,以控制3,4-二氯苯酚和3,4-二氯苯甲醇的间位选择性Suzuki偶联。已经开发了非共价相互作用引导的两性离子水环钯催化水中带有羟基的3,4-二氯芳烃的间选择性Suzuki偶联。实验和密度泛函理论(DFT)计算表明,静电相互作用在3,4-二氯苯酚的间选择性偶联中发挥着关键作用,而3,4-二氯苯甲醇的间选择性偶联是由于氢键相互作用而产生的。
