Thiol Vinyl Ether

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.

Thiol vinyl ether.

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. Thiol ene free radical and vinyl ether cationic hybrid photopolymerization macromolecules. Product name linear formula. Methoxy peg thiol methoxypolyethylene glycol thiol.

Poly methyl vinyl ether solution. Thiols r s h thiols r s h and sulfides r s r are sulfur analogs of alcohols and ethers respectively sulfur replaces oxygen. 1 product result match criteria. The thiol ene reaction also alkene hydrothiolation is an organic reaction between a thiol and an alkene to form a thioether.

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. These thiol ene polymerizations are photoinitiated without the use of photoinitiator molecules. 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. Interestingly the relative number of thiol functional group moles converted and the total.

Structure and properties of ethers the geometry around the o atom of an ether ror is similar to that. The advantages of the vinyl ether functionality is its capability to form stable or alternatively dynamic covalent bonds. 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. Ethyl isobutyl ether allyl vinyl ether.

A thiol monomer is shown to copolymerize with vinyl ether allyl acrylate methacrylate and vinylbenzene monomers. Vinyl ether functionalized cyclic phosphotriester monomer 2 ethylene glycol vinyl ether 1 3 2 dioxaphospholane 2 oxide evep 1 was synthesized by following a typical condensation method.
