One-pot odorless thia-Michael reaction by copper ferrite nanoparticle-catalyzed reaction of elemental sulfur, aryl halides and electron-deficient alkenes

Abstract

In this article we report a non-odorous protocol for the high yield formation of aryl–alkyl sulfides by the reaction of aryl iodides, bromides and boronic acids with elemental sulfur and electron-deficient alkenes, catalyzed by copper ferrite nanoparticles. The catalyst was easily separated using an external magnetic bar and recycled for subsequent runs, its catalytic activity being preserved.
