11. J. B. Beil and S. C. Zimmerman, Macromolecules, 2004, 37, 778. It should be noted that in the work of Beil and Zimmerman, 10 equiv. of Cu(I)Br are used for 8 initiator sites. Even if one copper is inserted into the porphyrin (a possibility not studied in the paper), there would still be an excess of copper per initiator (1.1 equiv.) and hence catalysis occurs. In addition, the basicity of the ligand may also play a role in the efficiency of copper insertion, when a stronger ligand is used the copper may not be extracted by the porphyrin.
12. The radical formed upon homolytic cleavage of the carbon-bromine bond must be immediately trapped since no conversion of styrene is observed. From entry 3, Table 1 it appears that a copper-porphyrin does not act as the radical trap; its precise nature is still under investigation.
