Tri- and Tetracarbanionic Initiators by a Lithium/Halide Exchange Reaction: Application to Star-Polymer Synthesis

A family of polycarbanionic initiators: Bis‐, tris‐, and tetrakisaryl lithium compounds (see scheme) were synthesized from the corresponding aryl halides by simple halogen/lithium exchange reactions. These polylithiated species were used to prepare telechelic and three‐ and four‐armed star polystyre...
