Aryl-lead(IV) triacetates react at room temperature with BF3·Et2O to give the corresponding arylfluoride 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 arylfluorides when stirred with lead tetra-acetate in BF3·Et2O.

the corresponding aryl fluoride in moderate to good yields; triarylboroxines, electron rich aryltrimethylsilanes and some arenes, which yield aryllead triacetates in acid catalysed reactions with lead tetraacetate, are converted directly into aryl fluorides when stirred with lead tetraacetate in BF3.Et2O. An investigation of the mechanism of the fluoro-deplumbation reaction indicates that it probably
