Highly efficient heterogenous catalyst for O-arylation of phenols with aryl halides using natural ferrous chamosite
Abstract Natural ferrous chamosite-catalyzed arylation of phenols with aryl iodides and bromides afforded the corresponding ethers in moderate to excellent yields. This ligand-free, natural catalyst catalyzed coupling of aryl iodides and aryl bromides with phenols resulted in high yields of diaryl ether formation in the absence of any additive. The catalyst was quantitatively recovered from the reaction by a simple filtration and reused for a number of cycles.
Graphical Abstract Display Omitted Research Highlights ► Natural ferrous chamosite, a naturally occurring marine clay serves as a catalyst. ► Catalyst for C-O bond formation for the synthesis of a wide variety of diaryl ethers. ► Recyclable and efficient catalyst with consistent activity. ► This ligand-free, natural catalyst catalyzed coupling of aryl iodides and aryl bromides with phenols. ► Affords excellent possible atomic economy when accounted with respect to substrate and product.
