Title:
FLUORIDATION OF ELECTRON RICH AROMATIC SYSTEMS
Document Type and Number:
WIPO Patent Application WO2005021472
Kind Code:
A3
Abstract:
The present invention provides a process for the fluoridation of the electron rich aryl group (A) in a diaryliodium salt of formula (I). The process comprises contacting a compound of formula (I) with a source of fluoride, wherein in the diaryliodium salt (1), the ring (B) is more electronegative than the ring (A).
