Even late transition metal complexes function as active and selective catalysts for α ‐olefin polymerization. The discovery of a highly active family of catalysts 1 based on iron, a metal that had no previous track record in this field, has highlighted the possibilities for further new catalyst discoveries. As a result, an intense search has developed for new‐generation catalysts, in both academic and industrial research laboratories. R 1 =H, Me; R 2 =Me, i Pr; R 3 =H, Me, i Pr; R 4 =H, Me; X=halide.
