Abstract

Aryl-lead (IV) triacetates react at room temperature with BF3· Et2O to give the corresponding aryl fluoride in moderate to good yields; triarylboroxines, electron-rich aryltrimethylsilanes, and some arenes, which yield aryl–lead (IV) triacetates in acid catalysed reactions with lead tetra-acetate, may be converted directly into aryl fluorides when stirred with lead tetra- acetate in BF3· Et2O.
