Application
α, α′-Dibromo-p-xylene may be used in the preparation of:
- third-generation bis(1-pyrazolyl)methane ligands
- 5,5′-[(p-phenylenedimethylene)dithio]bis(1-phenyl-1H-1,2,3,4-tetrazole)

A bis-chelating ligand (L1), made of two 7-(p-anisyl)-1,10-phenanthroline (phen) subunits connected with a p-(CH(2))(2)C(6)H(4)(CH(2))(2) spacer through their 4 positions, has been prepared, using Skraup syntheses and reaction of the anion of 4-methyl-7-anisyl-1,10-phenanthroline with alpha,alpha'-dibromo-p-xylene. Its Fe(II) complex, [FeL1(dmbp)](PF(6))(2), was prepared

The title 22-crown-6 unit, C(26)H(28)O(6), comprising of three benzo groups and triethyl-ene glycol, was prepared by the reaction of α,α'-dibromo-p-xylene with 1,8-bis-(2-hydroxy-phen-oxy)-3,6-dioxaoctane in the presence of Cs(2)CO(3) with tetra-hydro-furan (THF) and recrystallized from dichloro-methane-hexane (1:20 v/v) at room temperature. In
5, 5'-[(p-Phenylenedimethylene) dithio] bis (1-phenyl-1H-1, 2, 3, 4-tetrazole).
