Catalytic activity of some palladium complexes of a phosphorus ylide and structure of a 2-phenylaniline-based palladacycle complex
No full textA six-membered N,C-palladacycle bearing the 2-phenylaniline bidentate ligand (1) and three other palladium complexes of a phosphorus ylide (2, 3 and 4) were utilized in Suzuki reactions between phenylboronic acid and a number of aryl bromides and chlorides. The complexes were found to be capable homogeneous catalysts for a variety of substrates, affording the coupled products in good to excellent yields. The structure of compound I, determined by X-ray diffraction, is also reported
Quasi-3D free and forced vibrations of poroelastic microplates in the framework of modified couple stress theory
Get PDFIn this study, a comprehensive study on the vibration behaviour of functionally graded thick microplates with material imperfections is presented for free and forced vibrations within a quasi-3D model and the modified couple stress (MCS) theory. Axial, transverse, rotation, and stretching motions are considered for modelling the thick microplate in the framework of the modified power-law scheme and quasi-3D and MCS theories. The microplate deformation is assumed to be infinitesimal and is modelled using the linear strain–displacement relationships. Using a virtual work method, the governing motion equations are derived. For fourfold coupled (axial-transverse-rotation-stretching) characteristics, the partial differential equations components are discretised via trigonometric expressions and the corresponding natural frequencies and time histories (time-dependent deflections) are determined numerically. The methodology and model are initially validated through a comparative analysis between the natural frequencies of the macrolevel simplified structure and those obtained using finite element software. Additionally, the simulation is compared, for validation purposes, with other simplified versions from the literature. Once model's validity is confirmed, an investigation into the quasi-3D free and forced vibrations of the structure is conducted for the new model. The results demonstrate the considerable effect of thickness stretching and material imperfection on the vibration characteristics of the poroelastic thick microplates
Synthesis and Characterization of 2-Phenylaniline Cyclopalladated Complexes
No full textReaction of the dinuclear complex [Pd{kappa 2-N2',C1-2-(2'-NH2C6H4)C6H4}Cl](2) (1) with ligands (L = 4-picoline, sym-collidine) gave the six-membered palladacycles [Pd{kappa 2-N2',C1-2-(2'-NH2C6H4)C6H4}Cl(L)] (2). The complex 1 reacted with AgX (X = CF3SO3, BF4) and bidentate ligands [L-L = phen (phenanthroline), dppe (bis(diphenylphosphino)ethane), bipy(2,2'-bipyridine) and dppp (bis(diphenylphosphino) propane)] giving the mononuclear orthopalladated complexes [Pd{kappa 2-N2',C1-2-(2'-NH2C6H4)C6H4}(L-L)] (3) [L-L = phen, dppe, bipy and dppp]. These compounds were characterized by physicochemical methods, and the structure of [Pd{kappa 2-N2',C1-2-(2'-NH2C6H4)C6H4}Cl(L)] (L = sym-collidine) was determined by single-crystal X-ray analysis

[1,2-Bis(diphenylphosphanyl)ethane-κ2P,P′]{2-[(4-nitrobenzoylmethyl)diphenylphosphanyl]phenyl-κ2C,C′}palladium(II) trifluoromethanesulfonate–dichloromethane–n-hexane (1/1/0.5)
No full textIn the cation of the title compound, [Pd(C26H19NO3P)(C26H24P2)]CF3O3S·CH2Cl2·0.5C6H14, the PdII atom has a slightly tetrahedrally distorted square-planar coordination geometry. The PdC3P and PdC2P2 five-membered metallacycles adopt envelope and twist conformations, respectively. In the crystal, intermolecular C—H...O hydrogen bonds link cations and anions into a three-dimensional network. The dichloromethane solvent molecule is disordered over three orientations with a site-occupancy ratio of 0.5/0.3/0.2. The n-hexane solvent molecule has a crystallographically imposed centre of symmetry
