Description

General description

1,4-Difluoro-2,5-dimethoxybenzene is an alkoxy arene. It undergoes 1:3 reaction with TaF5 in chloroform at 40-50°C to afford long-lived radical cation salts [1,4-F2-2,5-(MeO)2C6H2][Ta2F11].

Application

1,4-Difluoro-2,5-dimethoxybenzene is suitable reagent used in a study to investigate the direct anodic electrodeposition of polypyrrole, poly(3,4-ethylenedioxythiophene) and polythiophene on Cu electrodes by employing a corrosion inhibitor. It may be used in the following studies:
• Synthesis of 7-fluoro-5,8-dimethoxy-1-naphthol.
• As novel precursor for the iterative double benzyne-furan Diels-Alder reactions.
• Synthesis of 1,4-bis(phosphino)-2,5-difluoro-3,6-dimethoxybenzenes.
