PhotOelectron Spectroscopy of Some trans-2,2'-Disubstituted Stilbenes*
نویسنده
چکیده
The He I photoelectron (PE) spectra of stilbene (1), 2,2'-dichlorostilbene (2) 2-amino-2'-chlorostilbene (3), 2,2'-diaminostilbene (4) ,and 2,2'-dinitrostilbene (5), all in their trans configuration are recorded and discussed. The electronic structure of 1-5 can well be described on the basis of the composite molecule method and simple Hiickel molecular orbital (HMO) calculations. Results indicate the importance of substituent effects causing characteristic shifts of low energy electronic band systems in the PE spectra.

Coordination chemistry for antibacterial materials: a monolayer of a Cu(2+) 2,2'-bipyridine complex grafted on a glass surface.
A propyltrimethoxysilane-modified 2,2'-bipyridine ligand is synthesized and its acetonitrile solutions are used to prepare monolayers of the molecule on glass surfaces. Absorption and X-ray photoelectron spectroscopy demonstrate that the modified glass surfaces bind Cu(2+) with a 1:1 ratio with respect to the 2,2'-bipyridine moieties under the chosen preparative conditions, producing materials ...

A convenient microwave irradiation protocol was utilized for the synthesis of b-ketosulfones 1-5 in good yields. These sulfones reacted with alkenes through a radical oxidative cyclization mediated by Mn(OAc)3. Dihydrofurans 6-10 were obtained in moderate to good yields starting from 1,1-disubstituted alkenes. Dihydrofurans 11-15 were synthesized in moderate yields and unexpected cyclopropanes ...

Oxidative Heck couplings have been successfully developed for 2,2-disubstituted cyclopentene-1,3-diones. The direct coupling onto the 2,2-disubstituted cyclopentene-1,3-dione core provides a novel expedient way of enantioselectively desymmetrising all-carbon quaternary centres.
متن کاملTheoretical study on the vibrational spectra of methoxy- and formyl-dihydroxy-trans-stilbenes and their hydrolytic equilibria.
Compounds formed by exchanging one of the resveratrol hydroxy groups to methoxy or formyl groups are biologically important. Quantum chemical DFT calculations were applied for the simulation of some of their properties. Their optimized structures and charge distributions were computed. Based on the calculated vibrational force constants and optimized molecular structure infrared and Raman spect...
