In organic solvents, converts arylamines directly to diazonium tetrafluoroborates which undergo the Balz-Schiemann reaction (see Tetrafluoroboric acid, L14037) in situ to give high yields of aryl fluorides: Chem. Ber., 88, 1939 (1955); EP 430,434 (1991). Methyl or methoxy substituted aromatics in acetonitrile give the nitrosoaromatics in good yield: J. Org. Chem., 59, 5573 (1994).
