Small change, big difference : The introduction of an additional CH 2 group into the bridge of ligands with two P/N units leads to a different selectivity of the corresponding chromium‐based catalysts. Whereas 1 produces an ethylene trimerization system, 2 provides an unprecedented ethylene tetramerization system that produces 1‐octene with high purity and little or no polymer side products (see scheme; DMAO=Me 3 Al‐depleted methylaluminoxane).
