一般描述

1,4-二氟-2,5-二甲氧基苯是烷氧基芳烃。它在40-50℃下与TaF5在氯仿中进行1:3反应,得到长寿命的自由基阳离子盐[1,4-F2-2,5-(MeO)2C6H2][Ta2F11]。

应用

1,4-二氟-2,5-二甲氧基苯是研究聚吡咯、聚(3,4-乙二氧基噻吩)和聚噻吩在铜电极上直接阳极电沉积的适宜试剂。它可用于以下研究:
  • 7-氟-5,8-二甲氧基-1-萘酚的合成。
  • 作为迭代双苄基-呋喃Diels-Alder反应的新型前体。
  • 合成1,4-双(膦基)-2,5-二氟-3,6-二甲氧基苯。

[reaction: see text] The use of 1,4-difluoro-2,5-dimethoxybenzene as a novel precursor for iterative two-directional benzyne-furan Diels-Alder reactions, using a range of 2- and 3-substituted furans, is reported. Substituted oxabenzonorbornadienes were synthesized following the initial Diels-Alder reaction, which upon ring opening
