An efficient access to 1,1-diarylethylenes of biological interest by coupling functionalized aryl Grignard reagents and 1-arylvinyl halides in the presence of FeCl3/CuTC is described. This bimetallic system proved to be superior to the use of Fe or Cu catalyst alone. The synthetic utility of this protocol is illustrated in the field of steroid chemistry.
描述了通过在FeCl 3 / CuTC存在下偶联官能化的芳基格氏试剂和1-芳基乙烯基卤化物来有效获得生物学上感兴趣的1,1-二芳基乙烯。事实证明,这种双金属系统优于单独使用Fe或Cu催化剂。该方案的合成用途在类固醇化学领域得到了说明。
