Benzene derivatives of the general formula STR1 where Hal is halogen, R1 is a hydrocarbon radical of 1 to 18 carbon atoms, R2 is hydrogen or alkyl of 1 to 6 carbon atoms and X is hydrogen or halogen, are prepared by a process in which a toluene derivative of the general formula STR2 is electrochemically oxidized in the presence of an acid of the formula R2 --COOH (III). Novel benzene derivatives of the general formula STR3 where R3 is hydrogen or an R2 --CO-- radical but R1 cannot be methyl if X is hydrogen, and of the general formula STR4 where R4 is a branched or cyclic alkyl radical of 3 to 12 carbon atoms, but R4 cannot be isopropyl if X is hydrogen. The compounds of formulas IV and VI are intermediates for crop protecting agents, e.g. pyrethroids.

Aliphatically substituted fluorobenzenes of the general formula I STR1 where R is an aliphatic or cycloaliphatic radical, n is 2, 3 or 4 and X is hydrogen, fluorine, chlorine or bromine, are prepared by diazotization of the corresponding aniline derivativ

The isopropylation of substituted benzenes by s-C3H7+ cations is studied to evaluate the directive effects of fluorine, methyl group and their combinations as ring substituents in the gas-phase aromatic substitution.
