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)
  • new bis 1,10-phenanthroline ligand (composed of two subunits of 7-(p-anisyl)-1,10-phenanthroline (phen) joined by p-(CH2)2C6H4(CH2)2 space groups at 4 positions), via Skraup synthesis
  • stereoisomers of α,α′-bis[3-(N,N-diethylcarbamoyl)-piperidino]-p-xylene
