Wolffenstein–Böters reaction
The Wolffenstein–Böters reaction is an
The reaction, which involves simultaneous
oxidation, was first reported by the German chemists Richard Wolffenstein and Oskar Böters in 1906.[4]
According to one series of studies the mercury nitrate first takes benzene to the corresponding
diazonium salt to the phenol. The presence of nitrite is essential for the reaction; picric acid formation is prevented when urea, a trap for nitrous acid, is added to the mixture. From then on the reaction proceeds as a regular aromatic nitration.[5][6]
A conceptually related reaction is the Bohn–Schmidt reaction, dating to 1889, which involves the hydroxylation of hydroxyanthraquinone with sulfuric acid and lead or selenium to a polyhydroxylated anthraquinone.
