| 摘要 |
A 3-halo-2-methylphenylmagnesium halide is cross-coupled with a halobenzene using nickel(II) acetylacetonate as catalyst, producing a 3-halo-2-methyl[1,1'-biphenyl]. The amount of catalyst should be greater than 0.01 mole percent, but not more than 0.1 mole percent, based on the 3-halo-2-methylphenylmagnesium halide to achieve the best yields.
