The effect of the penultimate unit on the CON bond homolysis rate constant k d was studied for model alkoxyamines. It was shown that the k d for fragments containing penultimate and antepenultimate units were nicely predicted by the tri‐parametric relationship developed in Macromolecules 2005 , 38 , 2638 and Eur. J. Org. Chem . 2006 , 7 , 1755 (log k d = −14.33 + 15.06 × σ RS + 20.00 × σ I + 6.96 × υ ). A striking effect was observed only for a tert ‐butyl‐like group as the penultimate unit.
