N'-[4'-benzo(15-crown-5)]-4-tolylaminoglyoxime (H2L1),the sodium chloride salt of H2L1 (H2L1...NaCl),N'-[4'-benzo(15-crown-5)]-4-chlorophenylaminoglyoxime(H2L2) and the sodium chloride salt of H2L2 (H2L2...NaCl)have been prepared from p-chlorophenylchloroglyoxime,p-tolylchloroglyoxime, 4'-aminobenzo[15-crown-5] and sodiumbicarbonate or sodium bicarbonate and sodium chloride. Nickel (II),cobalt (II) and copper (II) complexes of H2L and H2L...NaClhave a metal-ligand ratio of 1 : 2 and the ligand coordinatesthrough the two N atoms, as do most of the vic-dioximes. Their IR spectra and elemental analyses are given, together with1H NMR spectra of the ligands. 相似文献

Four unsymmetrical vic-dioximes: [L1H2] N-(4-butylphenyl)amino-amphi-glyoxime, [L2H2] N-(4-butylphenyl)amino-anti-glyoxime, [L3H2] N-(4-phenylazophenyl)amino-amphi-glyoxime and [L4H2] N-(4-phenylazophenyl)amino-anti-glyoxime have been prepared from amphi-chloroglyoxime, anti-chloroglyoxime, 4-butylaniline and 4-(phenylazo)aniline respectively. The complexes of these vic-dioximes with NiII, CoII, CuII and CdII ions have been investigated. All are insoluble in common solvents. Their i.r. spectra and elemental analyses are given, together with mass and 1H-n.m.r. spectra of the ligands. 相似文献

In the post Newtonian limit, a non-relativistic Hamiltonian is derived for scalar fields with quartic self-interaction and
non-minimal coupling to the curvature scalar of the background spacetime. These effects are found to contribute to the non-relativistic
Hamiltonian by adding nonlinearities and by modifying the gravitational Darwin term. As we discuss briefly in the text, the
impact of these novel structures can be sizable in dense media like neutron star core, and can have observable signatures
in phase transitions, for example. 相似文献

3‐Aminophenylcalix[4]pyrrole (3APCP) was grafted to a glassy carbon (GC) surface during the electrochemical oxidation process in 0.1 M tetrabutylammoniumtetra‐fluoroborate (TBATFB) containing acetonitrile solution. The presence of a surface film was confirmed electrochemically by comparing voltammograms of dopamine and ferricyanide redox probes at the bare and modified electrodes. Reflection‐absorption infrared spectroscopy (RAIRS), XPS, atomic force microscopy (AFM), ellipsometry and the contact angle measurements were also employed to characterize 3APCP film on GC electrode. RAIRS analysis revealed that calix[4]pyrrole was bonded to the glassy carbon surface via the etheric linkage. The stability of the modified GC electrode was also studied.

A concise and efficient synthesis of cyclooctane-1,2,3,4-tetraoles, new polyhydroxylated eight-membered carbocycles, is described starting from cis,cis-1,3-cyclooctadiene. Cyclooctene endoperoxide obtained by photooxygenation of cis,cis-1,3-cyclooctadiene was the key compound in the synthesis. Reduction of the endoperoxide with zinc or thiourea followed by acetylation of the hydroxyl group and OsO4/NMO oxidation of the double bond gave (1R(S),2S(R),3R(S),4S(R))-cyclooctane-1,2,3,4-tetraol. Interestingly, epoxidation of cyclooctene-1,4-diol with m-CPBA also afforded trans-epoxy-diol 17. (1R(S),2R(S),3R(S),4S(R))-cyclooctane-1,2,3,4-tetraol was easily obtained by hydrolysis of epoxy-diol 17. 相似文献
