Palladium compounds containing diphosphine ligand with N atom were immobilized on the surface of nano silica and MCM-41 resp. The resulting two novel heterogeneous Pd catalysts SiO2@ PNPPdCl2 (1) and MCM-41@ PNPPdCl2 (2) were fully characterized by SEM (EDX), TEM (SAED), XRD, FT-IR, ICP-Ms and TGA. Microstructure tests showed that the two kinds of nanoparticles have completely different structures, 1 has an irregular sphere structure and 2 has a honeycomb structure. The catalytic performance of nanoparticles 1 and 2 under mild conditions with EtOH/H2O (volume/volume=3/2) as solvent in Suzuki coupling reaction was further studied. The two catalysts had good group tolerance, and their average yields in four cycles were 81% (1) and 89% (2) resp. Their catalytic properties are also slightly different. The catalytic rate of catalyst 1 is much faster than that of 2, while catalyst 2 has better recycling performance. The experimental part of the paper was very detailed, including the reaction process of (3-Fluorophenyl)boronic acid(cas: 768-35-4Application of 768-35-4)
(3-Fluorophenyl)boronic acid(cas: 768-35-4) can be used to make novel liquid crystalline fluorobiphenylcyclohexenes and difluoroterphenyls by palladium-catalyzed cross-couplings also used in the synthesis of o-phenylphenols as potent leukotriene B4 receptor agonists.Application of 768-35-4
