One step synthesis of [7]metacyclophanediyne complexes from bis(propargyldicobalt) dication equivalents
Abstract
The BF3·OEt2 mediated addition reactions of electron-rich arenes to 1,3-dialkoxyhepta-2,5-diyne(dodecacarbonyl)- tetracobalt complex 1 directly afford [7]metacyclophanediyne(dodecacarbonyl)tetracobalt complexes.
