The bis(ylide)nickel complexes 1 catalyze acetylene polymerization. With respect to structure/activity relations, these one‐component catalysts reveal similarities between acetylene and ethene polymerization. The activity of this catalyst system exceeds that of all other acetylen polymerization catalysts based on Ni. With 1a in dimethyl sulfoxide at 60 °C and 1 bar, it was possible to convert 500 moles of acetylene per mole of nickel.
