adaptable networks (CANs) relies on the ability to trigger the rearrangement of bonds within a polymer network. Simple activated alkynes are now used as versatile reversible cross-linkers for thiols. The click-like thiol-yne cross-linking reaction readily enables network synthesis from polythiols through a double Michael addition with a reversible and tunable second addition step. The resulting thioacetal

The addition of thiols and amines to 3(2H)thiophenone 1,1-dioxide takes place with extrusion of sulfur dioxide,furnishing in high yields the corresponding vinyl sulfides and enamines. Addition of dithiols afforded the corresponding thioacetals. The rates of the the Michaeladdition and the extrusion reaction are strongly influenced by the solvent employed. In ethanol, sulfur dioxide extrusion took

synthesis of vinylogous thioesters was developed. 1-Alkylthio-3-silyloxybutadienes were then produced in high yields from the corresponding vinylogous thioesters. These dienes were highly reactive in Diels−Alderreactions, affording the cycloadducts in high endo selectivity under mild conditions.
