Highly efficient, recyclable Pd(II) catalysts with bisimidazole ligands for the heck reaction in ionic liquids

(Matrix presented) New Pd(II) complexes with bisimidazole ligands were prepared and proved to be effective catalysts for the Heck reaction under phosphine-free conditions using ionic liquids as solvents. This system could be recycled five times without any loss of catalytic activity.

Preoxidated polyacrylonitrile fiber mats supported copper catalyst for Mizoroki-Heck cross-coupling reactions

Porous preoxidated polyacrylonitrile (PAN) fiber mats, which was prepared by electrospinning and then followed by thermal treatment, has been used for the immobilization of copper catalyst. FT-IR/ATR spectra and XRD pattern show that the linear polymer structure of the PAN fiber mat can be converted into the ladder molecular structure at the high temperature. The morphology of the copper catalyst supported on the preoxidated PAN fiber mats was examined by scanning electron microscopy (SEM). The catalytic activity and stability of the fiber mat supported copper catalyst have been evaluated using the Mizoroki-Heck cross-coupling reaction of aryl iodides with different acrylates. It was found that the catalytic activities of fiber mat supported copper catalyst could be significantly promoted by addition of small amount of additives, such as ethylene glycol.

Polyacrylonitrile fiber mat-supported palladium catalyst for Mizoroki-Heck reaction in aqueous solution

A novel palladium catalyst immobilized on polyacrylonitrile fiber mats (Pd/PAN) was prepared by electrospinning. The catalytic activity and recyclability of the microwave-assisted Pd/PAN fiber mats were examined for the Mizoroki-Heck cross-coupling of ary

2-Hydroxy-1,10-phenanthroline vs 1,10-Phenanthroline: Significant ligand acceleration effects in the Palladium-Catalyzed Oxidative Heck reaction of arenes

A series of bidentate monoanionic nitrogen ligands were designed and applied in the Pd-catalyzed oxidative Heck reaction of arenes with alkenes. Significant ligand-accelerated effects were observed, and direct C-H functionalized products were formed in high yields with meta-selectivity.

Pd nanoparticles immobilized on poly(NIPAM-co-4-VP) hydrogel: Highly active and reusable catalyst for carbon-carbon coupling reactions in water

Poly(N-isopropylacrylamide-co-4-vinylpyridine) [poly(NIPAM-co-4-VP)] co-polymer exhibited inverse temperature solubility with a lower critical solution temperature (LCST) in water. Pd nanoparticles were immobilized on these poly(NIPAM-co-4-VP) hydrogels. The heterogeneous Pd catalyst showed high catalytic activities for carbon-carbon coupling reactions, such as Suzuki-Miyaura, Heck-Mizoroki, and Sonogashira coupling reactions in water. The Pd catalyst immobilized on poly(NIPAM-co-4-VP) hydrogel (NIPAM:4-VP = 1:1 M ratio) showed an excellent recyclability and excellent yield for carbon-carbon coupling reactions.

Pd-catalyzed ligand-free desulfitative Heck reaction with arenesulfinic acid salts under air

Palladium-catalyzed cross-coupling reactions of various aryl sulfinic acid salts with a wide variety of vinyl substrates have been achieved in good to excellent yields under simple aerobic conditions at 70°C with the assistance of Cu(II) salts. The reaction can be accelerated by the combination of DMSO with THF. The reported Matsuda-Heck type coupling reactions are tolerant to the common functional groups, making these transformations as attractive alternatives to the traditional cross-coupling approaches.

Aerobic oxidative coupling of arenes and olefins through a biomimetic approach

Arenes and electron-deficient olefins can be oxidatively coupled through a biomimetic Pd(OAc)2-catalyzed transformation. C-H activation of the arene partner is effected under reaction conditions of low catalyst loading, normal oxygen pressure,

Highly porous chitosan microspheres supported palladium catalyst for coupling reactions in organic and aqueous solutions

Porous chitosan microspheres (PCMS) were prepared from crosslinking chitosan/polyethylene glycol (PEG) interpenetrating microspheres through selective dissolution of the water-soluble PEG component for the immobilization of palladium catalyst. The resultant Pd/PCMS supported palladium has been demonstrated as a highly active and easily recyclable heterogeneous catalyst for the Ullmann-type reductive homocoupling of aromatic halides and the Heck cross-coupling of aromatic halides with acrylates. Most interestingly, the prepared Pd/PCMS heterogeneous palladium catalyst can also be employed in the environmentally-benign aqueous solution due to the highly hydrophilic hydroxyl and amino functional groups of chitosan. The large size of the microsphere structure can greatly facilitate separation and recycling of the expensive and toxic palladium catalysts from the reaction mixture and the recovered Pd/PCMS catalyst can preserve the catalytic activity and selectivity for the Heck reaction without any observable degradation over ten recycling times. The high activity and stability of the Pd/PCMS catalyst have been attributed to a combination of the high specific surface area of the porous structure as well as the strong chelation of palladium species with the abundant chitosan surface hydroxyl, amino and carbonyl functional groups.
