    • Arest-Yakubovich, A. A. J. Polym. Sci., Polym. Chem. Ed. 1997, 35, 3613. This reference contains the misleading assertion that aggregate reactivity in anionic polymerization has been long recognized. While this is in accord with the views of many, e.g., see refs 37 and 66-70, it is incompatible with the stance of the authors of refs 2-15. They have for more than 3 decades consistently maintained that associated organolithium headgroups (alkyl, aryl, and allylic) in hydrocarbon solvents do not react with styrenic and diene monomers under polymerization conditions.

    • Korotkov first offered the concept of monomer complexation with lithium headgroups: Koroykov, A. A. Angew. Chem, 1958, 70, 85. In our ref 8, p 360; this notion is deemed to be correct whereas on the following page the opposite conclusion is reached.
