Dispersity-controlled ring-opening polymerization of epoxide [PDF]
Dispersity or molar mass distribution (Ð M) profoundly influences polymer properties, but its control remains a challenge, especially for ring-opening polymerization (ROP).

Alkylative Aziridine Ring-Opening Reactions
In this study, the highly strained three-membered aziridine ring was successfully activated as the aziridinium ion by alkylation of the ring nitrogen with a methyl, ethyl or allyl group, which was followed by ring opening with external nucleophiles such ...

Recent advances using cyclopropanols and cyclobutanols in ring-opening asymmetric synthesis
Due to high ring strain energies, cyclopropanols and cyclobutanols have a strong tendency of breaking the endocyclic C–C bonds to participate in versatile organic transformations.

Carbodiimide Ring-opening Metathesis Polymerization
Controlled incorporation of nitrogen into macromolecular skeletons is a long-standing challenge whose resolution would enable the preparation of soft materials with the scalability of man-made plastics and functionality of Nature’s proteins. Nylons and polyurethanes notwithstanding, nitrogen-rich polymer backbones remain scarce, and their synthesis ...
