Reversible pyrrole-based proton storage/release in ruthenium(ii) complexes†
Abstract
Newly designed ruthenium(II) complexes are reported which contain a pyridylpyrrole ligand featuring fast-responsive and reversible proton storage/release on the pyrrole group. The protonated pyrrolium acts as an acidic initiator and is capable of triggering the polymerization of 2,2-dimethyloxirane.
