N′-tetramethylethylenediamine (1b)) have been synthesized by oxidative addition of trans,trans-2,5-distyryl-2,4-dibromobenzene to 2 equiv of “[Pd(dba)2]” (dba = dibenzylideneacetone) in the presence of the N∧N ligands. A similar reaction with N∧N = bpy = 2,2′-bipyridine afforded the mononuclear complex [PdBrC6H2(Br-4)((E)-CH═CHPh)2-2,5}(bpy)] (2). The reaction of 1a,b with PhC≡CPh, MeC≡CMe, and PhC≡CMe in the
