A magnetic palladium nickel carbon nanocomposite as a heterogeneous catalyst for the synthesis of distyrylbenzene and biphenyl derivatives

A magnetic palladium nickel carbon (Fe3O4@Pd@Ni/C) nanocomposite has been synthesized using a simple one-pot procedure via a hydrothermal approach. Ferric nitrate, palladium acetate, and nickel nitrate were dissolved in water together with glucose, and the mixture was heated in an autoclave. The Fe3O4@Pd@Ni/C nanocomposite was characterized via XRD, TEM, FE-SEM, VSM, EDS, and XPS studies. The catalytic abilities of the Fe3O4@Pd@Ni/C nanocomposite were investigated for the synthesis of distyrylbenzene and 9,10-distyrylanthracene derivatives. This method shows obvious advantages, such as the recyclability of the catalyst, simple experimental operation, and the obtaining of good to excellent yields.

Ruthenium-Sulfonamide-Catalyzed Direct Dehydrative Condensation of Benzylic C-H Bonds with Aromatic Aldehydes

The first catalytic dehydrative condensation of the benzylic C-H bonds of toluene and p-xylene with aromatic aldehydes is reported herein. This protocol provides highly atom-economical access to stilbene and p-distyrylbenzene derivatives, whereby water is the sole byproduct. The reaction is based on the deprotonation-functionalization of benzylic C-H bonds through η6-complexation of the arenes, which is realized for the first time using a catalytic amount of a transition metal activator. The key to the success of this method is the use of a sulfonamide anion as a catalyst component, which appears to facilitate not only the deprotonation of the benzylic C-H bonds but also the formation of a C-C bonds via an electrophilic tosylimine intermediate.

Comparison of 1,4-distyrylfluorene and 1,4-distyrylbenzene analogues: Synthesis, structure, electrochemistry and photophysics

A series of nine 1,4-distyrylfluorene derivatives (2) functionalized with substituents of variable electron-donating or -accepting capabilities was synthesised. The photophysical properties of the molecules were investigated, including UV/vis absorption,

Folded H-stacking polymers by conformational control with 2-substituted trimethylene tethers

Oligomers and polymers of type [-CH2CHRCH2-(π)-] n comprising aryl units tethered by 2-substituted trimethylene were found to exist as a folding H-stacking structure in polar solvents such as CH3CN and in film,

Fabrication of steady junctions consisting of α, ωbis(thioacetate) oligo(p-phenylene vinylene)s in nanogap electrodes

For obtaining molecular devices using metal-molecule-metal junctions, it is necessary to fabricate a steady conductive bridge-structure; that is stable chemical bonds need to be established from a single conductive molecule to two facing electrodes. In th

Photochemical behavior of some p-styrylstilbenes and related compounds: Spectral properties and photoisomerization in solution and in solid state

The spectral properties and Z,E-photoisomerizations of three 4-styrylstilbenes, a 4,4′-bis(β-methylstyryl)benzene and a 4,4′-distyrylstilbene were investigated in solution and in the solid state. Some notable features of the absorption and fluorescence sp

Palladium-catalyzed stereoselective synthesis of (E)-stilbenes via organozinc reagents and carbonyl compounds

In the presence of a catalytic amount of PdCl2(PPh 3)2 and a silylating agent, organozinc halides reacted with carbonyl compounds to give the corresponding (E)-stilbenes in good to excellent yields under mild conditions. The reaction mechanism is briefly discussed.

Bistable photoswitching in the film of fluorescent photochromic polymer: Enhanced fluorescence emission and its high contrast switching

The synthesis of aggregation-induced enhanced emission (AIEE)-based fluoroscent photochromic polymer, poly(DCS-BTE), whose strong fluorescence in the neat polymer film could photoswitched, was discussed. Polymeric film consisting of DCS in PMMA matrix were fabricated by spin-coating. Molecular planarization and J-type aggregation were observed in the DCS molecules gated by the specific intermolecular interactions in the solid state. The results show that the erasable fluorescence photoimaging on the spin-coated poly(DCS-BTE) film is successfully demonstrated.
