"S2": Generation and Synthetic Application

Sulfur allotrope chemistry - S10 an effective two-sulfur transfer reagent

The chemistry of one of the sulfur allotropes has been investigated. Cyclodecasulfur (S10) reacts with conjugated 1,3-dienes and strained olefins to deliver cyclic di- and polysulfides with a better selectivity and under milder conditions than with elemental sulfur (S8). A radical mechanism is proposed for these sulfuration reactions.

Quest for diatomic selenium

Metallocene pentaselenides and elemental selenium were employed in an effort to generate diatomic selenium (Se2) under thermal conditions. Trapping experiments were carried out with six dienes. A successful formation of a diselenium adduct was observed in the case of 5,6-dimethylene-cyclohexa-1,3- diene (1a). The other dienes produced the corresponding dihydroselenophenes. The in-depth study of the limitations of our method to generate Se2 is described; a plausible mechanism rationalizing the observed results is proposed.

Dialkoxy disulfides from cubycarbinols

Two dialkoxy disulfides 2 and 3 have been synthesized in respectable yields. The behaviour of 2 and 3 under thermal and photolytic conditions has been examined and we report the first examples of S2 liberation from aliphatic dialkoxy disulfides.
