Realistic amorphous models were constructed for CrIII single sites on a highly dehydroxylated SiO2 surface. The strain of the support plays a critical role in the initiation of ethylene polymerization. For more strained sites the insertion of ethylene into the CrO bond is the preferred pathway of ethylene polymerization. For less strained sites the CH activation of ethylene and the ethylene insertion into the CrO bond are competing pathways.
