✦ Synopsis

Chromium-based heterogeneous catalysts are used exten-alkyls containing a Cp*Cr III R fragment (Cp* = η 5 -C 5 Me 5 , pentamethylcyclopentadienyl) catalyze the polymerization of sively for the polymerization of olefins. There are few homogeneous model systems that allow investigation of the reac-ethylene and α-olefins. Correlations between molecular structure and catalytic activity are reviewed. tion mechanisms and unique characteristics of chromium catalysts. Coordinatively unsaturated paramagnetic chromium MICROREVIEWS: This feature introduces the readers to the authors' research through a concise overview of the selected topic. Reference to important work from others in the field is included.
