“…In some cases the reactions with ortho-ethynylpyridine gave as byproduct the unexpected binuclear FePd μ-pyridylvinylidene complex [Cp(CO)Fe{μ(2)-η(1)(C(α)):η(1)(C(α))-κ(1)(N)-C(α)[double bond, length as m-dash]C(β)(H)(o-C(5)H(4)N)}(μ-CO)PdI]. The conditions, catalysts, and reagents that provide the highest yields of the desired σ-pyridylethynyl iron compounds were determined. …”

“…Kinetics study on the hydrogenation of furfural diethyl acetal over Pd/SiO(2) and Na(+) doped Pd/SiO(2) suggested that the Na(+) greatly impeded the hydrogenolysis of C–O–C bond of acetal, while the hydrogenation of the furan ring took place selectively.…”

“…It is found that the OH stretching bands of water are decomposed into four components, and while the higher-frequency components (with peaks at ∼3610 and ∼3540 cm(–1)) behave in parallel with the C=O and C–O–C stretching and CH deformation bands of the polymers, the lower-frequency components (with peaks at ∼3430 and ∼3260 cm(–1)) become pronounced to a greater extent with increasing humidity. …”

“…[Image: see text] A pyrene dimer (PYD) is synthesized by electrochemical oxidation via homocoupling of pyrene (PY) inside the pores of MgO-templated mesoporous carbons without any metal catalysts or organic solvents. The resulting MgO-C/PYD hybrids can be used as high-performance aqueous electrochemical capacitor electrodes due to the reversible redox property of PYD and large contact area between the hybridized PYD and conductive carbon surfaces, which enable rapid charge transfer at the large contact interface. …”
