Deoxygenation of dithiirane 1-oxides with Lawesson's reagent leading to the corresponding dithiiranes.
3,3-Disubstituted dithiirane 1-oxides were efficiently reduced with Lawesson's reagent (LR) to give the corresponding dithiiranes. X-ray diffraction analysis of 3,3-di(1-adamantyl)dithiirane is reported. Reaction of (34)S-labeled 3,3-di(1-adamantyl)dithiirane 1-oxide with LR produced the corresponding dithiirane in which the (34)S atoms were retained quantitatively.
