Abstract

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.
