摘要: Abstract Treatment of trisubstituted (Z)-bromoalkenyl-pinacolboronates with terminal alkynes in the presence cuprous iodide, palladium(0) tetrakis(triphenylphosphine) and Hunig’s base leads to formation 1,2,4,6-tetrasubstituted aromatic compounds a one-pot fashion. Substrate scope was shown for three four alkynes.
