SHORT COMMUNICATIONSuzuki Reactions of Aryl Bromides Catalyzed by Hydroxyapatite-Supported Manganese

Add time:08/29/2019    Source:sciencedirect.com

Suzuki cross-coupling reactions between aryl bromides and phenylboronic acids were studied over a hydroxyapatite-supported Mn catalyst (MnHAP) for the first time. An increased yield was obtained over the fluoride ion-exchanged hydroxyapatite-supported Mn catalyst (MnFAP). Under optimized conditions, the yield was about 70%. The effect of solvent compositions and different substituents were studied over the MnFAP catalyst. The DMF-H2O mixture with a DMF/H2O volume ratio of 1/3 was the best solvent. Moderate yields (18%–46%) were obtained for all tested aryl bromides and phenylboronic acids substituted by different groups.
