Reaction of thallium(I) bromide with aromatic Grignard reagents which are unsubstituted in the ortho positions results in rapid reduction of the inorganic halide to metallic thallium and simultaneous formation, in high yield, of symmetrical biaryls. A sequence of redox reactions among the three thallium valence states is shown to be involved in the overall coupling process. The scope and limitations
溴化al(I)与在邻位未取代的芳族格氏试剂的反应导致无机卤化物快速还原成金属al,并同时高产率地形成对称的联芳基。三个coupling价态之间的一系列氧化还原反应被证明与整个偶联过程有关。已经定义了该联芳基合成的范围和限制。
