화학적 성질
yellow powder주요 응용
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.
용도
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.
