In the absence of any activator , [Cp*Cr(C 6 F 5 )(η 3 ‐Bn)] (Cp*=C 5 Me 5 ; Bn=benzyl) promotes the “Aufbaureaktion” under ethylene to produce linear alkyl products (see scheme). The molecular‐weight distribution of the resulting ethylene oligomers is narrow and in good agreement with that predicted by the Poisson distribution formula. Thus this novel system displays features of a living polymerization.
