Chromium‐based heterogeneous catalysts are used extensively for the polymerization of olefins. There are few homogeneous model systems that allow investigation of the reaction mechanisms and unique characteristics of chromium catalysts. Coordinatively unsaturated paramagnetic chromium alkyls containing a Cp*Cr III R fragment (Cp* = η 5 ‐C 5 Me 5 , pentamethylcyclopentadienyl) catalyze the polymerization of ethylene and α‐olefins. Correlations between molecular structure and catalytic activity are reviewed.
