Linear 2:1 co-oligomerization between an acrylate and an alkyne can be achieved using certain nickel complexes but, as for cobalt, it is difficult to predict whether a cyclic or a linear compound will be isolated at the end of the process. Nevertheless, 1,3,5-trienes are obtained from interactions between alkenes, alkynes, and nickel complexes [NiX2(PPh3)2 (X = Cl, Br, I)] in contact with zinc dust; for example, the triene 33 is available when 2.8 molecular equivalents of ethyl acrylate are combined with a single equivalent of 1-phenylprop-1-yne using diiodobis(triphenylphosphine)nickel(II) as the catalyst (Scheme 12)[20].
