    • For a boron-containing alkoxide as polymerization regulator, see: T. C. Chung, W. Janvikul, H. L. Lu, J. Am. Chem. Soc 1996, 118, 705. Boron does modulate the reactivity of the alkoxyl radical, however, does not directly interact with the radical. Therefore, this process should not be regarded as a boron group transfer reaction.

    • eff is the effective concentration of the V-70 derived initiating radicals and 141 corresponds to the molecular weight of the initiating moiety. We assume that about 35 % of the radicals that derive from V-70 do not act as initiating species, and instead undergo in-cage dimerization, With 1 equiv of V-70, we assume that within 1 h at 70°C around 1.3 equiv of initiating radicals are available for the polymerization process.

    • Unfortunately, all attempts to oxidize the polymeric boron enolate with TEMPO failed so far. We recently reported (see Ref. [11]) that in B-enolate formation/TEMPO-trapping process about 10% of reduced enone was always formed. The mechanism of that reduction is currently still, not understood
