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.

Fabrication of nanocrystals from diolefin derivatives and their solid-state photoreaction behavior

Nanocrystals of seven p-phenylenediacrylates, i.e., dimethyl (la), didecyl (lb), diundecyl (1c), ditetradecyl (1d), dipentadecyl (1e), dioctadecyl (1f), and dicholesteroyl (1g) derivatives, and 2,5-distyrylpyrazine (2) were fabricated by the reprecipitation method and their photochemical reaction behaviors were investigated in comparison to those of bulk crystals. The bulk crystals of 1a- 1c and 2 were found to be photoreactive, whereas those of 1d-1g were less photoreactive. In contrast, all of the nanocrystals of 1a-1g and 2 showed high photoreactivity. Nanocrystals of la and 2 were demonstrated to have the same packing as the corresponding polymerizable bulk crystals, and they gave the corresponding polymers by photoirradiation. The polymer crystal structures in their nanocrystals were confirmed to be the same as those in bulk crystals by X-ray and electron diffraction analyses. Their single-crystal-to-single-crystal transformation was established by their nanocrystallization. On the other hand, other nanocrystals (1b-1g) were found to have different packings compared with the corresponding bulk crystals. After photoirradiation, their crystallinity was degraded to form amorphous products.

Synthesis and Properties of 4,4,9,9-Tetramethylparacyclophane-5,6,7,8-tetrone

The synthesis of 4,4,9,9-tetramethylparacyclophane-5,6,7,8-tetrone (26) has been achieved in a multistep procedure.Compound 26 is the first cyclic tetraketone whose structure has been studied by X-ray analysis.The key intermediates were 4,4,9,9-tetramethylparacyclophane-6,7-dione (22), 6,7-bis-4,4,9,9-tetramethylparacyclophane-5,7-diene (24), and two epimeric 5,8-dihydroxy-4,4,9,9-tetramethylparacyclophane-6,7-diones 25a and 25b.X-ray analyses have been performed on 24, 25b and 26.That on 24 reveals a dihedral angle of 57 deg between the two silyenol ether groups.The product analyses and the configurations of 25a and 25b together with the isolation of the bis(epoxide) intermediate 28 allow conclusions to be drawn on the oxidation mechanism of 24 with m-CPBA (Rubottom reaction).The stability of 26 is ascribed to steric factors.
