General description

α,α′-Dibromo-p-xylene, also known as p-xylylene dibromide, is an aliphatic dihalide that serves as a versatile intermediate in organic reactions, including the synthesis of aromatic ionene polymers and dual-site phase-transfer catalysts.

Application

α,α′-Dibromo-p-xylene can be used as a building block to synthesize:      
  • Phthalazinone derivatives, which are reported as potent inhibitors of phosphodiesterase 4.    
  • N-Phenylated polyamine via polycondensation reaction with aniline and α, α′-dianilino-p-xylene.     
  • Porous polymeric network (PPN) via a Friedel-Crafts alkylation reaction with triphenylamine using FeCl3 as an oxidizing agent.
