Abstract: Abstract We describe a convenient method for the synthesis of symmetrical and unsymmetrical conjugated 1,3-diynes from cross-coupling reactions of organoaluminum with alkynylhalides: The cross-coupling reaction of organoaluminum (0.75 mmol) with alkynylhalides (0.5 mmol) mediated by Ni(acac)2 (5 mol%)/DPPE(10 mol%)… read more here.
