Exploring the Reactivity\nof Electrophilic Organic\nCarbonates and Thiocarbonates as Vehicles to Convert Hydrosulfide\ninto COS and CS<sub>2</sub>

Hydrogen\nsulfide (H<sub>2</sub>S) and other reactive sulfur species\nare important small molecules with biological significance. In addition\nto common reactive sulfur species like H<sub>2</sub>S, polysulfides,\nand persulfides, both carbonyl sulfide (COS) and carbon disulfide\n(CS<sub>2</sub>) have been postulated to be potential sources of reduced\nsulfur. To better understand this possible connection, we demonstrate\nthat H<sub>2</sub>S can be converted to COS and CS<sub>2</sub> by\nreaction with simple organic carbonate and thiocarbonate electrophiles,\nrespectively.
