Radikalionen, 79 [1, 2]. ESR-Nachweis von Tetra(methylthio)thiophen- und Tetra(methylthio)ethen-Radikalkationen bei der oxidativen Schwefelung von H3CS-C=C-SCH3 mit S2Cl2/AlCl3 und H3CSCl/AlCl3
Radical ions, 79 [1, 2]. ESR evidence for tetra(methylthio)thiophene and tetra(methylthio)ethene radical cations during the oxidative sulfuration of H3CS-C=C-SCH3 by S2Cl2/AlCl3 and H3CSCl/AlCl3
- Di(methylthio)acetylene H3CS-C≡C-SCH3 reacts with S2C12 in AlCl3/H2CCl2 solution to the tetra(thiomethyl)thiophene radical cation (H3CS)4C4S·⊕ and with H3CSCl to the tetra(thiomethyl)ethene radical cation (H3CS)2C·=⊕C(SCH3)3. Their ESR spectra are assigned by comparison with literature data or those of analogous products obtained from other acetylene derivatives R-C≡C-R with R = SCH2CH3, CH3, C6H5 as well as based on HMO arguments. The possible course of the oxidative sulfuration is discussed.
