Palladium(0) Nanoparticles Embedded in Core-shell Nanogels as Recoverable Catalysts for the Mizoroki-Heck Reaction

Mechanisms of the Mizoroki–Heck Reaction

The palladium-catalysed Mizoroki–Heck reaction is the most efficient route for the vinylation of aryl/vinyl halides or triflates. This reaction, in which a C C bond is formed, proceeds in the presence of a base (Scheme 1.1) [1, 2]. Nonconjugated alkenes are formed in reactions involving cyclic alkenes (Scheme 1.2) [1e, 2a,c,e,g] or in intramolecular reactions (Scheme 1.3) [2b,d–g] with creation...

Bimetallic Pd-Ni core-shell nanoparticles as effetive catalysts for Suzuki reaction

Imprinted nanogels as biomimetic catalysts

The term ‘biomimetic’ is commonly used to describe instances in which a chemical process imitates a biochemical reaction and has attracted considerable interest as more and more scientists study Nature’s phenomena and mechanisms. The design and synthesis of catalytic systems capable of mimicking enzyme’s activity while overcoming some of the protein’s inherent limitations is an important challe...

Labeling of alprenolol with fluorescent aryl iodide as a reagent based on Mizoroki-Heck coupling reaction.

A novel fluorescent labeling method for alprenolol was developed based on Mizoroki-Heck coupling reaction. We designed and synthesized fluorescent aryl iodide, 4-(4,5-diphenyl-1H-imidazol-2-yl)iodobenzene (DIBI) as a labeling reagent. DIBI has a lophine skeleton carrying an iodide atom acting as fluorophore and reactive center, respectively. In order to evaluate the usefulness of DIBI, a high-p...

Core-shell Au-Pd nanoparticles as cathode catalysts for microbial fuel cell applications

Bimetallic nanoparticles with core-shell structures usually display enhanced catalytic properties due to the lattice strain created between the core and shell regions. In this study, we demonstrate the application of bimetallic Au-Pd nanoparticles with an Au core and a thin Pd shell as cathode catalysts in microbial fuel cells, which represent a promising technology for wastewater treatment, wh...
