NITRO DERIVATIVES OF FLUOROBENZENE

The most important nitro derivatives of fluorobenzene are:

m. p. 27°C m. p. 25.8°C m. p. 35°C

The nitration of fluorobenzene was studied by a number of authors. Most of
the earlier work was devoted to mononitration (Wallach [44], Hollernan [45],

Swarts [46]).

Dinitration to obtain 1,2,4-fluorodinitrobenzene was described by Holleman

and Beekman [47] who nitrated p- fluoronitrobenzene. Zahn and A. Würz [48]

prepared the same dinitrocompound by nitrating fluorobenzene. 1,2,4,6-Fluorotrini-

trobenzene (picryl fluoride) was prepared by Olah, Pavlath, J. Kuhn and Varsanyi

[49] by acting on 1,2,4-fluorodinitrobenzene with a nitrating mixture composed

of fuming nitric acid and 60% oleum. The yield was 36% of theoretical.
