Polystyrene supported N-phenylpiperazine-Pd(II) complex D was synthesized and characterized by various techniques, including Fourier transform infrared spectroscopy (FTIR), scanning electronmicroscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and thermal analysis (TG-DTA). This heterogeneous Pd(II) complex showed high catalytic efficiency for the Suzuki-Miyaura coupling of arylboronic acids with aryl bromides, aryl chlorides to give the corresponding 2-arylpyridines and heteroarenes. The coupled products were formed in excellent yields at low catalyst loadings under mild reaction conditions. Further, this heterogeneous catalyst showed excellent recyclability and reused for four cycles with no significant decrease in its activity.

Synthetic Route of 4721-98-6, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.4721-98-6, Name is 6,7-Dimethoxy-1-methyl-3,4-dihydroisoquinoline, molecular formula is C12H15NO2.

Considering current economical and ecological contexts, the questions of setting up clean and eco-efficient processes as well as saving our energy resources appear to be of fundamental importance. We need to develop reactions that would address the problem of the selective transformation of chemicals under mild conditions. This urges industries to develop “green chemistry” procedures that have not only to include catalytic processes to limit waste, but also to use harmless solvents, the ideal of which would be water, with low temperatures and pressures to limit energy consumption. Such conditions are already fulfilled by enzymes, including metalloenzymes. Because the properties of enzymes are complementary to those of chemical catalysts, it is conceivable to design catalysts that would combine the robustness and wide range of reactions of chemical catalysts with the ability of enzymes to work under mild conditions in aqueous medium and with high selectivity. Many teams have been working on the conception of hybrid biocatalysts, obtained by association of a protein with a synthetic molecule. This chapter reviews the three strategies explored to obtain the kind of hybrid biocatalysts that are artificial metalloenzymes. Catalysis by artificial metalloenzymes in cascade reactions is covered in the last paragraph.

A collection of substituted potassium internal vinyltrifluoroborates was prepared and utilized in palladium-catalyzed cross-coupling reactions with aryl and heteroaryl halides. The cross-coupling reactions proceeded readily with Pd(PPh3)4 as a catalyst in toluene/H2O under reflux in the presence of Cs2CO3. The process is regiospecific with regard to the internal vinyltrifluoroborate starting material and tolerates a variety of functional groups. This unique collection of substituted internal vinyltrifluoroborates can be readily utilized in research pharmaceutical applications.

The Pd-catalyzed cross-coupling of thiols with aromatic electrophiles is a reliable method for the synthesis of aryl thioethers, which are important compounds for pharmaceutical and agricultural applications. Since thiols and thiolates strongly bind late transition metals, previous research has focused on catalysts supported by chelating, bisphosphine ligands, which were considered less likely to be displaced during the course of the reaction. We show that, by using monophosphine ligands instead, more effective catalysis can be achieved. Notably, compared to previous methods, this increased reactivity allows for the use of much lower reaction temperature, soluble bases, and base-sensitive substrates. In contrast to conventional wisdom, our mechanistic data suggest that the extent of displacement of phosphine ligands by thiols is, first, not correlated with the ligand bulk or thiol nucleophilicity and, second, not predictive of the effectiveness of a given ligand in combination with palladium.

The low loading combination of the complex [9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene] (Xantphos)copper(I) iodide and simple ligand-free palladium(II) acetate was found to be efficient for the domino synthesis of diarylalkynes by the reaction of aryl halides with trimethylsilylethynylene or bis(trimethylsilyl)acetylene in a single-step procedure. The unsymmetrical diarylalkynes can be obtained through a one-pot two-step approach. The reactions of aryl bromides with 1,4-bis(trimethylsilyl)butadiyne also furnished the corresponding 1,4-diaryl-1,3-diynes in a similar fashion. This route to diarylalkynes and 1,4-diaryl-1,3-diynes is complementary to previously reported synthetic procedures. (Figure presented.).

Copper-catalyzed vinylation of 2- and 4-hydroxy pyridine and quinoline affords exclusively N-vinylation products. However, vinyl ethers of 4-hydroxy pyridine and quinoline can be prepared via a three-step sequence involving copper-catalyzed C-O cross coupling reaction of the corresponding N-heteroaryl bromides with ethylene glycol, chlorination of the terminal alcohol, and dehydrohalogenation of the beta-chloro ethers. Although not efficient in 2-hydroxy series, this method can be conveniently applied to the preparation of various aza-aryl vinyl ethers in moderate to good overall yields.
