Determination of aromaticity indices of thiophene and furan by nuclear magnetic resonance spectroscopic analysis of their phenyl esters was written by Lee, Chang Kiu;Yu, Ji Sook;Lee, Hye-Jin. And the article was included in Journal of Heterocyclic Chemistry in 2002.Computed Properties of C8H7BrO2 This article mentions the following:
A series of m- and p-substituted Ph benzoates, 2-thienoates, and 2-furoates were prepared and their 1H and 13C NMR spectroscopic characteristics were examined In general, good correlations were observed between the chem. shift values of protons and carbons of the acyl aromatic rings and the Hammett σ. Plots of the chem. shift values of the carbonyl carbons of the benzoates against those of the 2-thienoates and 2-furoates gave an excellent correlation and the values of the slopes are 0.85 and 0.75, resp., in DMSO-d6 and 0.90 and 0.78, resp., in chloroform-d. The values could be considered as a set of aromaticity indexes. In the experiment, the researchers used many compounds, for example, 3-Bromophenyl acetate (cas: 35065-86-2Computed Properties of C8H7BrO2).
3-Bromophenyl acetate (cas: 35065-86-2) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
