摘要

Abstract Through the use of [PdCl (C 3 H 5)] 2/cis, cis, cis-1, 2, 3, 4-tetrakis [(diphenylphosphanyl) methyl] cyclopentane as a catalyst, a range of vinyl bromides undergo Suzuki cross-couplings with arylboronic acids in good yields. Furthermore, the catalyst can be used at low loadings, even for reactions of sterically hindered substrates. Mediated by this catalyst, stilbene and 1, 1-diphenylethylene undergo Heck reactions with ...
