To establish transmetalation and the purity of the resulting arylsilver complex, we also prepared previously characterized 2,4,6-trimethylphenylsilver tetramer, which participated in fluorination under the same reaction conditions as 2 (see Supporting Information for details).

    • Byproducts resulting from C-H instead of C-F bond formation, as found for the Ag-mediated fluorination of arylstannanes, were not observed in the fluorination of boronic acids reported here. C-H bond formation in the Ag-mediated fluorination of arylstannanes is not due to the presence of water and cannot be suppressed by the addition of molecular sieves. We have determined that Bu3SnOTf is involved in C-H bond formation. Transmetalation from arylboronic acids to Ag in methanol produces B(OMe)3, which does not provoke C-H bond formation
