| Abstract: | An efficient access to 1,1-diarylethylenes of biological interest by coupling functionalized aryl Grignard reagents and 1-arylvinyl halides in the presence of FeCl(3)/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. |
