| Abstract: | A study of the coupling reaction of substituted halobenzenes with a zero valent pyridine-nickel complex as catalyst, leading to biphenyl derivatives, has been made. Electron-releasing groups as substituents favor the formation of coupling products in low yields, while electron-withdrawing groups as substituents suppress the formation of dimers.
