  The present invention provides an activator in arylamination using a palladium compound as a catalyst, which is superior to conventional phosphines in stability and performance. With the phosphine sulfide as an activator, an arylamination reaction achieves improved selectivity to produce a desired aromatic amine in an obviously increased yield as compared with a reaction using the corresponding phosphine compound. Moreover, the phosphine sulfide of the invention is impervious to oxidation and exists stably in air and therefore sufficiently withstands use on an industrial scale.

  本发明提供了一种在芳基化反应中使用钯化合物作为催化剂的活化剂，其在稳定性和性能方面优于传统的膦化合物。通过使用膦硫化物作为活化剂，芳基化反应实现了改善的选择性，以明显增加的产量生产所需的芳香胺，与使用相应的膦化合物的反应相比。此外，本发明的膦硫化物不受氧化影响，在空气中存在稳定，因此足以在工业规模上使用。
• Selective and Efficient Direct Fluorination of Polycyclic Aromatic Hydrocarbons Using 1-Fluoro-4-hydroxy-1,4-diazoniabicyclo[2.2.2]octane Bis(tetrafluoroborate)
  作者：Stojan Stavber、Marko Zupan

  DOI：10.1246/cl.1996.1077

  日期：1996.12

  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.
