A green and efficient Pd-free protocol for the Suzuki-Miyaura cross-coupling reaction using Fe3O4@APTMS@Cp2ZrClx(x=0, 1, 2) MNPs in PEG-400

摘要

In this paper, a new application of the Fe3O4@APTMS@Cp2ZrClx(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.
