    Abstract: A phenyl ester is produced by allowing benzene, a carboxylic acid and molecular oxygen to react with each other in the presence of a catalyst comprising (A) palladium, (B) at least one element selected from elements of groups IIIb, IVb, Vb and VIb of the periodic table, and (C) at least one element selected from elements of groups IIIa and IVa of the periodic table. Preferably, element (B) is selected from elements of group VIb of the periodic table, and element (C) is contained in a metal oxide form in the catalyst. The catalytic activity can be maintained at a high level, and a phenyl ester is stably produced. The phenyl ester can be converted to phenol by a conventional procedure.

    Abstract: A phenyl ester is produced by allowing benzene, a carboxylic acid and molecular oxygen to react with each other in the presence of a catalyst comprising (A) palladium, (B) at least one element selected from elements of groups 13, 14, 15, and 16 and the fourth to sixth periods of the periodic table, and (C) at least one element selected from elements of groups 3, 4 and lanthanoid elements of the periodic table. Preferably, element (B) is selected from elements of group 16 and the fourth to sixth periods of the periodic table, and element (C) is contained in a metal oxide form in the catalyst. The phenyl ester can be converted to phenol by hydrolysis or ester exchange.
