Description

应用

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.
