Reaction Steps
In the same autoclave as used in Example 1, 50 ml of benzene, 0.98 g of maleic anhydride and 0.019 g of Rh4 (CO)12 were charged, followed by supply of carbon monoxide under 30 kg/cm2. The charge in the autoclave was heated at 220° C. for 7 hours. The reaction mixture was cooled and benzene was removed by distillation under reduced pressure. The residue was separated by silica column chromatography to obtain 0.363 g of phenylmaleic anhydride and 0.136 g of succinic anhydride. Each product was identified based on the infrared absorption spectrum (hereinafter referred to as "IR") of the standard substance and the retention time in GC.
