Tetramethylthiuram sulfide is an organosulfur compound with the formula ((CH3)2NCS)2S. It is a yellow solid that is soluble in organic solvents. It is the parent member of a large class of tetraalkylthiuram sulfides.[1]
Synthesis and structure
It is prepared by desulfuration of tetramethylthiuram disulfides with triphenylphosphine or cyanide:
- (Me2NCSS)2 + PPh3 → (Me2NCS)2S + SPPh3
According to X-ray crystallography, the molecule consists of two planar (CH3)2NCS subunits joined by a sulfide. The dihedral angle between the subunits is close to 90°.[2]
