Bromoquinolines (2-bromoquinoline ? 8-bromoquinoline and 5-bromo-3-methoxyquinoline) and 2-aminophenylboronic acid hydrochloride were subjected to Suzuki-Miyaura cross-coupling conditions resulting in formation of the desired biaryl systems in good yields. The resulting biaryls were then subjected to palladium catalyzed C?H activation/C?N bond formation utilizing PdCl2(dppf). The reactions revealed large differences in reactivity depending on the attachment point for the 2-aminophenyl group on the quinoline. The variation in the reactivity was rationalized based on the electron distribution around the quinoline ring-system.

High-melting-point alkylammonium tetrafluoroborates melt with water or toluene to form biphasic mixtures at much lower temperatures than their normal melting points, thus could serve as green reaction media for Suzuki and Heck couplings. Advantages of using the aqueous-ammonium biphasic catalytic system include: (1) working well with a ligandless palladium catalyst, (2) solving the solubility problem of organic substrates and (3) simplifying work-up procedures for both separation of products and recycling of reaction media.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, name: [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 72287-26-4, Name is [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), molecular formula is C34H28Cl2FeP2Pd

The synthesis, structures, and optical and electrochemical characteristics of novel crown-containing styryl mono-and polythiophenes were described. The double bonds were constructed by the Horner-Wadsworth-Emmons method. The Suzuki and Stille cross-coupling reactions were used to create polythiophene chains. Optical measurements revealed intense absorption and fluorescence of crown-containing polythiophenes; the band positions and shapes in their absorption and emission spectra depend on the structure of the polythiophene. The electrochemical characteristics of the compounds obtained were measured.

The first direct arylation via C-OH bond activation of tautomerizable heterocycles has been achieved using phosphonium salts, on the basis of a combination of the phosphonium coupling and Suzuki-Miyaura cross-coupling conditions. Optimal reaction condition is obtained through screening of phosphonium salts, Pd catalysts, and bases. The direct arylation via C-OH bond activation tolerates a variety of tautomerizable heterocycles and aryl boronic acids. The mechanism of the Pd-catalyzed phosphonium coupling is proposed to proceed via a domino seven-step process including the unprecedented heterocycle-Pd(II)-phosphonium species. Application of the Pd-catalyzed direct arylation via C-OH bond activation using PyBroP leads to the most efficient synthesis of the biologically important 6-arylpurine ribonucleoside in a single step from unactivated and unprotected inosine.
