In the following composition:
Cl_CH2_S=O_CH2_Cl
in H-NMR: H`s are diastrotapic and :d of d? because S is Chiral? or singlet?
Grossert and Langler (The sulfohaloform reaction. The stepwise conversion of dialkyl sulfides into alkanesulfonyl chlorides. Can. J. Chem. Vol. 55, 1977) give 4.57 ppm, q., J=11.0Hz for 1,3-dichloro-2-thiapropane-2-oxide.
Good luck in your research. AF
Michael, my sentiments exactly! Still, I would love to see an actual high-resolution 1H spectrum of 1,3-dichloro-2-thiapropane-2-oxide that might further elucidate the multiplet structure. (In some of the early literature doublet of doublets were also called "quartets" as they had four lines.) Resolution enhancement might even reveal 37,35Cl isotope effects.
Best wishes, Tony
Clemens, if you are successful getting this compound and and its spectrum, please let us know. Thanks, Tony.
