    • We obtain these values when we assume that each active catalyst molecule produces only one polymer chain. Therefore, they are the upper limit and the real initiation efficiencies might actually be much smaller if chain transfer takes place.

    • For most conformations, displacement along the reaction coordinate from the transition state leads directly to β-, γ-, or δ-C-O coordination.

    • E will be only poorly stabilized by coordination of the solvent (dichloromethane or chloroform). We assume that the solvent effect that is included by use of the COSMO model will account well enough for this.

    • The yields of the oligomers cannot be determined directly (see the Experimental Section) and therefore exhibit a significant experimental error. However, we think this error is smaller than the increase of yield that we observe for the polymer.
