Proton transfers are key elementary steps in ethylene polymerization on isolated chromium(III) silicates

Mononuclear Cr(III) surface sites were synthesized from grafting [Cr(OSi(O(t)Bu)(3))(3)(tetrahydrofurano)(2)] on silica partially dehydroxylated at 700 °C, followed by a thermal treatment under vacuum, and characterized by infrared, ultraviolet-visible, electron paramagnetic resonance (EPR), and X-r...
