Radical-anions of the isomeric 9-substituted thioxanthen S-oxides
Abstract
Radical-anions of 9-substituted thioxanthen S-oxides have been prepared and their e.s.r. spectra measured. For the two 9-methyl isomers the S–O group has the pseudoaxial conformation, in contrast to its pseudoequatorial conformation in the neutral compounds. The spectra of decomposition products are also observed.
