Aromatic hydrocarbons and compounds

Under pro tic conditions, aromatic hydrocarbons and compounds with activated double bonds usually undergo Birch-Kke reactions [172]. The reaction sequence has been elucidated by the classical work of Hoijtink [15-17, 173, 174], who used the HMO theory to rationalize both chemical and electrochemical steps. 

In order to overcome certain difficulties such as the dissipation of heat and the use of inflammable mixtures, certain liquid phase processes have been proposed for the oxidation of aromatic hydrocarbons and compounds. In such a process 100 the aromatic hydrocarbons or their halogenated derivatives are treated with air or gas containing free molecular oxygen in the liquid phase at temperatures above ISO0 C. and under pressure in the presence of a substantial quantity of liquid water. A small quantity of such oxidation catalysts as oxides or hydroxides of copper, nickel, cobalt, iron or oxides of manganese, cerium, osmium, uranium, vanadium, chromium and zinc is used. The formation of benzaldehyde from toluene is claimed for the process.
