Abstract

In this paper, a new application of the Fe₃O₄@APTMS@Cp₂ZrCl_{x(x = 0, 1, 2)} MNPs as a robust and highly efficient Pd-free catalytic system in the environmentally benign Suzuki–Miyaura cross-coupling reaction has been demonstrated. The use of the recyclable Pd-free catalyst and PEG-400 as a green solvent, relatively short and acceptable reaction times, and good-to-excellent yields of the pure bi-aryl products are some of the salient features of the current carbon–carbon cross-coupling synthetic strategy.

使用PEG-400中的Fe 3 O 4 @ APTMS @ Cp 2 ZrCl x（x = 0、1、2）MNPs进行的铃木-宫浦交叉偶联反应的绿色高效无钯方案

摘要

在本文中，Fe ₃ O ₄ @ APTMS @ Cp ₂ ZrCl _{x（x = 0，1，2）} MNPs在环境友好的Suzuki-Miyaura交叉催化系统中作为强大而高效的无Pd催化体系的新应用。已经证明了偶联反应。使用可回收的无钯催化剂和PEG-400作为绿色溶剂，相对短且可接受的反应时间以及纯联芳基产品的良好至优异的收率是当前碳的一些突出特征–碳交叉耦合合成策略。
