Depolymerization Linear polysiloxanes with tunable molecular weights can be obtained via a facile thiol‐ene reaction that serves as a promising complement to traditional ring‐opening polymerization. The reaction involves selective oxidation of sulfides into sulfones by using an inexpensive reagent under safe and mild conditions without the need for additional reagents.
