✦ Synopsis

Cyclopropyl radicals normally undergo complete thermodynamic equilibration of configuration before they react, e.g., with bromine in the Hunsdiecker reaction'. Incomplete equilibration is normally due to steric or cage effectsa, and to surface effects when cyclopropyl halides are reduced with metals 3,4 .

Jacobus and Pensak, however, proposed that an optically active tertiary

## Abstract **Summary:** The possibility of transforming a living anionic polymerization into a stable radical‐mediated radical polymerization (SFRP) was demonstrated. For this purpose, 2,2,6,6‐tetramethylpiperidine‐__N__‐oxyl (TEMPO) alcoholate, formed by a one‐electron redox reaction between pota
