Structure and spectra of vinyl sulfides

Polymers from S-vinyl monomers: reactivities and properties

“…This effect can be explained by the 2p–3p conjugation of sulfur and the adjacent carbon atom. However, this conjugation is much weaker in the ground state than the 2p–2p conjugation of oxygen to the adjacent carbon in vinyl ethers, so a reaction with radicals is favored and the new electron-distributing conjugation in the transition state leads to the stabilization of the radicals by the participation of the 3d orbitals of sulfur, what could also be confirmed later by Shorygin et al 45…”

The reactivity of the monomers can be calculated from the ratio of the different monomers in the polymer compared to the original composition of the monomer mixture.…”

Raman Spectrometry

“…and the influence of substituents upon the Raman spectra examined (74,144,171,174,195). Similar attention has been given to vinyl sulfides (173,196). Nukada (157) has concluded that only one rotational isomer exists for dimethoxymethane, ethoxymethoxymethane, and diethoxymethane but two isomers exist (158) for the corresponding 1,1-dialkoxyethanes.…”
