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.
Reacts with diols to give cyclic thionocarbonates which are desulfurized by trialkyl phosphites to give alkenes by cis-elimination of CO2 from the intermediate carbene (Corey-Winter olefination): J. Am. Chem. Soc., 85, 2677 (1963); Angew. Chem. Int. Ed., 14, 753 (1975). For a modified procedure involving ring-opening of the thionocarbonate intermediate with an alkyl iodide, followed by Zn reduction of the resulting iodo ester, see: Tetrahedron Lett., 3793 (1973). Alternatively, the thionocarbonate of a 1,2-diol can be selectively reduced to the methylenedioxy group with Triphenyltin hydride, L00163, under free-radical conditions: J. Org. Chem., 62, 4159 (1997).
Can be used to deoxygenate carbocyclic monosaccharide analogues: Tetrahedron., 48, 2349 (1992).
