A SELF-SUPPORTED PALLADIUM-BIPYRIDYL CATALYST FOR THE SUZUKI-MIYAURA COUPLING IN WATER

摘要

A self-supported palladium catalyst (PdCl2BPy-Cu) was prepared via construction of a metal-organic framework (MOF) of a bipyridyl-palladium complex bearing carboxylic groups and a copper(II) linker. PdCl2BPy-Cu efficiently catalyzed the Suzuki-Miyaura coupling of phenyl halides with arylboronic acids in water under atmospheric conditions to afford the corresponding biaryl products in high yield. The catalyst was reused four times without loss of catalytic activity.
