    compounds were fully characterized by 1H, 13C1H} NMR and FT-IR spectra. The structures of 2c, 2d, and 2e were determined by X-ray crystallography and the prepared complexes (2a-e) were investigated as catalysts for the direct arylation of 2-n-propylthiazole, 4,5-dimethylthiazole and 2-acetylthiophene with various aryl bromides. High catalytic activity for arylation was seen reaction using only 0.5 mol%

    Palladium associated with cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane (Tedicyp) was found to promote the direct 2-arylation of a variety of thiophene derivatives via CH functionalisation in good yields using very low catalyst loadings. Electron-deficient, electron-excessive or sterically-congested aryl bromides are tolerated. Moreover, several substituents on the aryl bromide

  • From agriculture residue to catalyst support; A green and sustainable cellulose-based dip catalyst for C C coupling and direct arylation
    作者:Vishal Kandathil、Manjunatha Kempasiddaiah、Sasidhar B. S.、Siddappa A. Patil

    The core characteristics of a perfect catalyst include good activity, simple design, excellent stability, easy recovery from reaction mixture, recyclability, and have the provision for easy scale up. The ease in synthesis, recyclability and scale up makes the dip catalyst a major contender in this regard which possess most of the aforementioned characteristics. In this work, we report a dip catalyst made of cellulose, isolated from agriculture residue (sugarcane bagasse), in which biogenically synthesized palladium nanoparticles were dispersed. The prepared dip catalyst was characterized by FESEM, EDS, XRD, ATR-IR, TGA, TEM, XPS and ICP-OES analysis. Also, the activity of the dip catalyst was studied in the Suzuki-Miyaura cross-coupling reaction and was found to give excellent conversion with 15 recycles. Further, the activity of dip catalyst in C5-arylation of 2-substituted thiophenes was evaluated for which promising yields were obtained.
