Description and Uses

1,1'-Thiocarbonyldiimidazole (TCDI) is an imidazole compound that can be prepared by reacting thiophosphoryl chloride with two corresponding imidazoles.  Its structure has two imidazole rings, and the imidazole groups can be rapidly displaced, making it a safer alternative to thiophosphoryl chloride.  TCDI is used as an organic synthesis or chemical reaction reagent for the synthesis of thiosemicarbazones and thioamides.  It is also used in the Corey-Winter olefin synthesis and in the Barton-McCombie deoxygenation reaction.  In addition, it is the sulfur analogue of the peptide addition reagent carbodiimidazole (CDI), which is used to couple peptides.

1,1’Thiocarbonyldiimidazole can be used to deoxygenate carboxylic monosaccharide analogues.
