Complexation-Initiated Intramolecular Diels−Alder Reaction

, 2016
A complexation-initiated intramolecular Diels−Alder reaction was demonstrated for the first time. On adsorbing the alkyne−Co2(CO)6 complexes having a diene and a dienophile on opposite ends of the alkyne on silica gel, the Diels−Alder reaction was ...

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

Macromolecular 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.
