Entropy-driven ring-opening olefinmetathesispolymerizations of macrocycles

Abstract

The curious entropy-driven ring-opening metathesis polymerization (ED-ROMP) of macrocyclic olefins is highlighted. From early proof-of-principle reports through current state-of-the-art studies with an inclination towards materials applications, the known examples of these uncommon polymerizations are surveyed. The underpinnings of why these reactions work, what is and what is not to be expected and the prevailing practical measures to be taken to favor ED-ROMPs are discussed.
