ABSTRACT:
Biphenyl or nucleus-substituted biphenyl can be prepared from benzene or nucleus-substituted benzene and oxygen or oxygen-containing gas in one step according to an equation ##SPC1##
Wherein X is H, lower alkyl having 1 to 6 carbon atoms Cl, NO.sub.2, or lower alkoxy having 1 - 3 carbon atoms and Y is H or CH.sub.3, with excellent yield by heating the reactants in the presence, as a catalyst, of palladium or a palladium compound and sulfuric acid or sulfuric acid and a lower saturated fatty acid added to the reaction system and further in the presence or in the absence of an alkali metal salt.
