Reaction of 8-mercurio-1-naphthalenecarboxylate with iodide or bromide ions in aqueous acetic acid yields the corresponding 8-halogenomercurio-l-naphthalenecarboxylic acid together with 1-naphthalenecarboxylic acid and not the 8-halogeno-l-naphthalenecarboxylic acid. 相似文献

Magnetic Co nanoparticles with different morphologies were synthesized in a novel solution system using a UV irradiation technique. By adjusting the compositions in the solution, long nanowires with different aspect ratios as well as spherical nanoparticles with controllable particle size could be obtained. 相似文献

The ruthenium complexes, [(eta5-C5R5)Ru(CH3CN)3]PF6 (1-Cp*, R = Me; 1-Cp, R = H), underwent reaction with both 1-(2-chloro-1-methylvinyl)-2-pentynyl-(Z)-cyclopentene (6-Z) and 1-(2-chloro-1-methylvinyl)-2-pentynyl-(E)-cyclopentene (6-E) to give (eta5-C5R5)Ru[eta6-(5-chloro-4-methyl-6-propylindan)]PF6 (7-Cp*, R = Me; 7-Cp, R = H). In a similar fashion, reaction of 1-Cp and 1-Cp* with 1-isopropenyl-2-pent-1-ynylcyclopentene (8) led to the formation of (eta5-C5R5)Ru(eta6-4-methyl-6-propylindan)]PF6 (9-Cp*, R = Me; 9-Cp, R = H). The reaction of 1-Cp* with 8 at -60 degrees C in CDCl3 solution led to observation of the eta6-dienyne complex, (eta5-C5Me5)Ru[eta6-(1-isopropenyl-2-pent-1-ynylcyclopentene)]PF6 (10), by 1H NMR spectroscopy. Complexes 7-Cp and 10 were characterized by X-ray crystallographic analysis. 相似文献

The technique of ferromagnetic resonance at 23 GHz has been used to determine the first three anisotropy constants of pure Ni down to 4.2K. A temperature and orientation dependent linewidth has also been observed. 相似文献

Abstract Angle resolved energy spectra for H+ 2 scattering from Au(110) have been compared to simulations using MARLOWE and SABRE binary collision codes. The results of both simulations agree with each other but only qualitatively with the experiment. The simulations indicate that (i) contributions to the surface peak in the energy spectra come from both single and double scattering at the surface (ii) the amount of inelastic loss suffered by the scattered ion is sensitive to the loss model and (iii) azimuthal scans around the double alignment direction can be simulated quite well if an increased experimental background is included. 相似文献
