Abstract

The use of sodium in silica gel enables an efficient synthesis of symmetrical disulfanes from organic thiocyanates at room temperature. This protocol provides an attractive alternative to existing methods for the preparation of symmetrical disulfanes as it avoids the use of foul-smelling thiols.
