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 (TCDI) is generally used as a reagent to carry out the deoxygenation of vicinal diols by forming cyclic thionocarbonate in Corey-Winter alkene synthesis.It is used as a reagent in the enantioselective total synthesis of (+)-hapalindole Q, 12-epi-fischerindole U and welwitindolinone A.
It is also used in the preparation of trithiocarbonates, xanthates, and dithiocarbamates as chain transfer agents for the reversible addition fragmentation chain transfer and macromolecular design (RAFT/ MADIX) polymerization.
??
1,1'-Thiocarbonyldiimidazole is used as a reagent for the deoxygenation of alcohols with tributyltin hydride and diols with lithium aluminum hydride. It is also used to deoxygenate carboxylic monosaccharide analogues. Further, it is a useful reagent involved in biochemical synthesis. In addition to this, it is used to prepare 1-[bis-(4-methoxy-phenyl)-methyl]-1H-imidazole by reacting with 4,4'-dimethoxy-benzhydrol.Purification Methods
It forms yellow crystals on recrystallisation from tetrahydrofuran or by sublimation at 10-3torr (bath temperature 70-80o). It is hydrolysed by H2O and should be stored dry.
