Sun-light-driven Suzuki-Miyaura Cross-coupling using a Novel Superparamagnetic Metal-organic Framework Catalyst

A prominent catalytic activity for sun-light driven Suzuki-Miyaura cross-coupling reaction has been shown in the presence of superparamagnetic core-shell metal-organic framework ([Fe.sub.3][O.sub.4]@Ni-Co-BTC NPs) (with particle size 10-47 nm) and unique bimetallic core-shell nanostructure). Various...

Description
Summary:A prominent catalytic activity for sun-light driven Suzuki-Miyaura cross-coupling reaction has been shown in the presence of superparamagnetic core-shell metal-organic framework ([Fe.sub.3][O.sub.4]@Ni-Co-BTC NPs) (with particle size 10-47 nm) and unique bimetallic core-shell nanostructure). Various aryl halides with electron-donating or electron-withdrawing substituents were coupled with different arylboronic acids towards corresponding products at ambient temperature in [H.sub.2O]. The results of photocatalysis demonstrate that [Fe.sub.3][O.sub.4]@Ni-Co-BTC NPs is a good photocatalyst under sun light irradiation with high efficiency, chemoselectivity and functional group tolerance. This magnetic separable nanostructured catalyst can be reused more than six times with minimal loss of catalytic activity rendering this catalyst long-term stability. The results acquired in the present study can serve as inspiration for the further exploitation of the sun-light-driven cross-coupling reaction under mild conditions. Keywords: superparamagnetic core-shell metal-organic framework ([Fe.sub.3][O.sub.4]@Ni-Co-BTC NPs), Suzuki-Miyaura cross coupling reaction, photocatalysis, aryl halides, arylboronic acid, sun-light-driven reaction.
