Nitronium salts protosolvation

Olah, G. A., Laali, K. K., and Sandford, G. (1992a). Comparison of the nitration of poly-fluoronitrobenzenes by nitronium salts in superacidic and aptotic media Activation of the nitronium ion by protosolvation. Proc. Natl. Acad. Sci. U.S.A. 89, 6670-6672. [Pg.78]

Superacidic FSO3H (fluorosulfonic acid, Ho — 15) has also been used in some studies involving superelectrophilic activation. However, due to its tendency for sulfonation and oxidation, this acid has found only limited use in synthetic conversions involving superelectrophiles. Fluorosulfonic acid has been shown effective to activate nitronium salts in their reactions with weak nucleophiles, and again it was suggested that the protosolvated species (6) is involved in the reactions.28 Both fluorosulfonic acid and triflic acid have been reported to give the diprotonated species (14) from 3-arylindenones (eq 12) 29... [Pg.85]
