  • Title: Iron catalyzed highly regioselective dimerization of terminal aryl alkynes.
    Author: Midya GC, Paladhi S, Dhara K, Dash J.
    Journal: Chem Commun (Camb); 2011 Jun 21; 47(23):6698-700. PubMed ID: 21552588.
    Abstract:
    Iron can catalyze head-to-head dimerization of terminal aryl alkynes to give the corresponding (E) selective conjugated enynes in high yields. A variety of substituted aryl acetylenes underwent smooth dimerization using catalytic FeCl(3) and DMEDA in the presence of KO(t)Bu.
