| 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. |
| 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. |
