The combination of CS2, t-BuOK and DMSO as solvent mediates
a reduction of unsaturated ketone derivatives to provide saturated ketones. The
in situ generation of xanthate salts through the reaction of carbon disulfide
and potassium tert-butoxide is essential. Deuterium-labeling experiments
demonstrated that DMSO can act as a hydrogen donor.

Phenyliodine(III) diacetate (PIDA) initiates a disproportionate coupling of
readily available and inexpensive sulfonyl hydrazides to provide thiosulfonates
in very good yields. This transition-metal-free synthesis involves cleavage of
the S-N bond and formation of a new S-S bond. The thiosulfonates were further
reduced with CS2/KOH to obtain symmetrical disulfides.
