bis(tetrafluoroborate) (AccufluorTM NFTh) was effectively used for selective fluorination of polycyclic aromatics. Naphthalene was site-selectively fluorinated to 1-fluoronaphthalene, phenanthrene to 9-fluorophenanthrene, and pyrene to 1-fluoropyrene. In a series of substituted naphthalenes the regioselectivity and effectiveness of fluorination depended on the position and the nature of the substituents.
一种新的NF氟化试剂1-氟-4-羟基-1,4-重氮二环[2.2.2]辛烷双(四氟硼酸盐)(AccufluorTM NFTh)有效地用于多环芳烃的选择性氟化。萘经位点选择性氟化为 1-氟萘,菲为 9-氟菲,芘为 1-氟芘。在一系列取代的萘中,氟化的区域选择性和有效性取决于取代基的位置和性质。
