The oxidative coupling of some ortho-substituted phenyllithium with ferric acetylacetonate was reported. This novel method of aryl-aryl coupling has advantages of readily available reagent

mild reaction conditions

and good yield of coupling products. Thus

di-tert-butyl 1

1’-biphenyl-2

2’-dicarboxylate

N

N-dimethyl benzylamine aind 2

2’-bis(N

N-dimethylaminomethyl)-1

1’-biphenyl had been dimerized by the method with satisfactory yield. The experimental details were described in this article.
