Thiol Vinyl Ether

Methoxy peg thiol methoxypolyethylene glycol thiol.

Thiol vinyl ether.

Interestingly the relative number of thiol functional group moles converted and the total. These thiol ene polymerizations are photoinitiated without the use of photoinitiator molecules. 1 product result match criteria. Thiols r s h thiols r s h and sulfides r s r are sulfur analogs of alcohols and ethers respectively sulfur replaces oxygen.

The advantages of the vinyl ether functionality is its capability to form stable or alternatively dynamic covalent bonds. Thiol ene free radical and vinyl ether cationic hybrid photopolymerization macromolecules. The thiol ene reaction also alkene hydrothiolation is an organic reaction between a thiol and an alkene to form a thioether. C 3 h 6 o n.

The kinetics of the vinyl and upe group reactions are mirrored by the thiol conversion in figure 12 a which exhibits a very rapid initial loss of thiol groups reaction with vinyl ether followed by a much slower conversion reaction with upe. Structure and properties of ethers the geometry around the o atom of an ether ror is similar to that. Coupling of ethylene glycol vinyl ether eve to 2 chloro 3 oxo 1 3 2 dioxaphospholane cop in the presence of triethylamine tea in dichloromethane dcm. A thiol monomer is shown to copolymerize with vinyl ether allyl acrylate methacrylate and vinylbenzene monomers.

While thiol ene reactions of vinyl ethers with various thiols yield robust thioether linkages viareaction at the β carbon reactions with thiols or alcohols in the presence of acid. P toluenesulfonic acid ptsa induced a cationic thiol ene reaction to generate a thioacetal in high yield whereas 2 2 azobisisobutyronitrile resulted in a radical thiol ene reaction to give a thioether also in high yield. Poly methyl vinyl ether solution. The sequential thiol vinyl ether copolymerization and the vinyl ether cationic polymerization result in cross linked networks with thermal and mechanical properties that are combinations of each system.

This reaction was first reported in 1905 but it gained prominence in the late 1990s and early 2000s for its feasibility and wide range of applications. Ethyl isobutyl ether allyl vinyl ether.
