Study On The Copper(Ⅱ) And 2,2'-Biimidazolyl-Promoted Ullmann Coupling Reaction For The Synthesis Of Diaryl Ether And Arylamine

In this article, a series of diaryl ethers and arylamines weresynthesized by the reactions of Aryl iodides and phenols or primaryamines as the substrates under the assistance of Cu(â…¡) and 2, 2′-biimidazole. Excellent results were obtained. The structures of theproducts were confirmed by ¹H NMR, ¹³C NMR and MS spectra data.
