실험 절차

This example was carried out under the same reaction conditions as in Example 1 except that 29.0 g of 4,4'-dimethyldiphenyl ether, 0.067 g (0.30 m. mole) of palladium acetate, and 0.030 g of acetylacetone (0.30 m. mole) were employed and the mixture was reacted for 7 hours. As a result, 5.9 g (30 m. moles) of 2,8 -dimethyldibenzofuran was obtained and 1.9 g (4.7 m. moles) of the dimer also obtained.
