    • Polymer cyclization by a click chemistry. See: refs 6c-1. The reaction between one unit of an eight-armed star precursor and four units of a bifunctional end-linking reagent reportedly produced a quatrefoil (spiro-tetracyclic) polymer product. If this could happen, the star precursor should react with exactly four end-linking reagents in the course of the reaction. See: Ge, Z.; Wang, D.; Zhou, Y.; Liu, H.; Liu, S. Macromolecules 2009, 42, 2903-2910.

    • A cyclic poly(THF) having an alkyne group was previously synthesized by the post-functionalization of a ring polymer (ref 23), while in the present study, a dicarboxylate counteranion having an alkyne group (2a) was employed for an ESA-CF process to form Ia.
