N.M.R. spectra of symmetrical ortho disubstituted benzenes dissolved in the nematic phaseN.M.R. spectra of ortho dibromo, dichloro and dicyano benzenes have been studied in liquid crystalline nematic phases. The spectra have been analysed iteratively. The direct couplings are found to be of ...

The separation of benzene derivatives is energy intensive and laborious as a result of the overlapping physicochemical properties of these isomers. Here, we report on the separation of ortho-disubstituted benzene isomers using cucurbit[7]uril (CB7) aqueous solution with more than 92% selectivity. Th...
Within this context, crystal structures of spatially overcrowded ortho-disubstituted benzene derivatives with chloromethyl or methylamino groups are presented together with semiempirical enthalpy hypersurfaces for the substituent rotation. Both compounds, 1 -trichloromethyl-2-dichloromethyl-benzene as well as l...
If you’re planning a synthesis of a disubstituted benzene derivative containing an ortho-, para- director and a meta–director, you need to choose the order of operations wisely: To obtain the para–(or ortho- ) product —-> install the ortho- , para- director first To obtain the meta...
