Abstract

The ^13^C NMR spectra of four thiocarbamates and their corresponding S‐oxides and S, S‐dioxides are reported. Both β~SO~ and β effects are deshielding and range from 20.44 to 21.68 ppm. The β~SO~′ effects are slightly deshielding (0.20 ∼ 0.0.77 ppm). The β′ effects, on the contrary, are shielding and range from −6.54 to −6.98 ppm. The γ′, δ′, ξ′, and ζ′ effects are also discussed.
