Vinylogous urethane based vitrimers are polymer networks that have the intrinsic property to undergo network rearrangements, stress relaxation and viscoelastic flow, mediated by rapid ...

A new three-way bond-breaking and making mechanism makes the synthesis of five-membered rings easier than before.

Reductive elimination reactions, in which a transition metal catalyzes new bond formation between two molecules, are one of organic chemists’ most powerful tools. For example, one flavor of these ...
