Cyclopalladated ferrocenylimine was tested as catalyst in the Ullmann-type coupling reaction in the presence of 1Pr2NEt as base and DMF as solvent under Ar conditions. The preparation of aromatic iodide comprises: diazotization reaction of substituted aniline with aqueous sodium nitrite solution in the presence of concentrated sulfuric acid to obtain substituted iodobenzene, adding with potassium iodide, placing in refrigerator for 2-3 h, adjusting with NaOH to alk., extracting with dichloromethane, drying with anhydrous magnesium sulfate. It offered excellent yields in the coupling reaction of electronically and structurally diverse aryl iodides. Herein we have developed a simple, efficient way to synthesize sym. biaryls.
