Abstract

A novel ligand-free copper-catalyzed Mizoroki-Heck cross-coupling reaction of various aryl iodides with olefins has been developed. Both the solvent and the base were found to have a fundamental influence on the efficiency of the transformation in the presence of 10 mol% Cu2O, with DMF and tetramethylammonium bromide (TMAB) being the optimal solvent and base, respectively. As a result, a set of the corresponding E-internal olefins were obtained selectively in moderate to good yields.
