cyclopentene moiety undergo indium(III)‐catalyzed Friedel–Crafts‐type cyclization with subsequent ring expansion and dehydrogenation to afford fluorinated polycyclic aromatic hydrocarbons in high yields. The introduction of an Ar group was effected by in situ halogenation of the intermediary indium species and a subsequent Suzuki–Miyaura reaction.
颇为狡猾:带有芳基和环戊烯部分的1,1-二氟丙烯经过铟(III)催化的Friedel-Crafts型环化,随后扩环和脱氢,从而以高收率得到氟化的多环芳烃。Ar基团的引入是通过中间铟物种的原位卤化和随后的Suzuki-Miyaura反应实现的。
