A novel synthesis of selenosulfides from diselenides by samarium diiodide
Guo,Zhang
, p. 374 - 375 (2007/10/03)
Diselenides were reduced by samarium diiodide in tetrahydrofuran (THF) to produce samarium selenolate. This selenolate anion reacted smoothly with sodium alkyl thiosulfates and phenylsulfenyl chloride to give selenosulfides in moderate to good yields.
