ZnBr₂‐Catalyzed Efficient Oxidative Homo Coupling of Aryl Magnesium Bromides

IICT Communication No. 050507

Abstract

Oxidative homo coupling of various arylmagnesium bromides in the presence of ZnBr₂ gave the corresponding symmetrical biaryls in moderate to good yields at room temperature. An efficient method under mild conditions without the use of reoxidant is described.
