The Serendipitous Discovery of Rollover Cyclometalation: From Unrecognized Observation to Transformative Chemistry

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Rollover cyclometalation is a distinctive variant of classical cyclometalation where a chelated heterocyclic ligand undergoes internal rotation, releasing one donor atom from coordination and subsequently activating a remote C─H bond with high regioselectivity.

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

open access: yesMacromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Thiolate Salt Mediated Dynamic Silyl Ether Exchanges for Polymer Network Design and Deconstruction

open access: yesMacromolecular Rapid Communications, EarlyView.
This work introduces thiolate salts as mediators for dynamic silyl ether exchange. This platform enables the synthesis of reprocessable covalent adaptable polymer networks (CANs) and allows for sterically controlled, and tunable deconstruction of silyl ether‐containing thermosets.

Sulfur‐Rank‐Dependent Dispersion and Precipitation Behavior of Structurally Defined Sulfur‐Containing Polymers

open access: yesMacromolecular Rapid Communications, EarlyView.
Poly(vinylpyrrolidone) creates a quasi‐stable dispersion copolymerization system that enables direct comparison of the dispersed and precipitated polymer fractions. Structural analysis shows that fractionation correlates more strongly with sulfur rank than with molecular weight, revealing how the number of consecutive sulfur atoms in the polysulfide ...
