PURPOSE:To obtain the subject compound useful as an intermediate for pharmaceuticals, agricultural chemicals, etc., with simple process in high yield at a low cost by using an aromatic compound having isopropenyl group as a raw material and oxidizing the material with oxygen in the presence of a catalyst. CONSTITUTION:The objective compound can be produced by using an aromatic compound having isopropenyl group as a raw material and oxidizing the material with oxygen (preferably air) in the presence of a catalyst. The amount of oxygen is preferably reaction equivalent or more. The catalyst is preferably produced by supporting a transition metal (e.g., chromium, copper or manganese) on a carrier in the form of a compound or ion. Especially preferably, the catalyst is a lamellar clay mineral subjected to ion-exchange with a transition metal ion. The reaction is carried out preferably by charging the raw material, catalyst and solvent in a reaction vessel, introducing oxygen into the vessel under pressure while stirring the content and oxidizing the raw material at 100-200 deg.C (preferably 120-160 deg.C) under 5-50kg/cm<2> pressure. |
