|Section2= |Section3= |Section8= }} Tetrahydrothiophene is an organosulfur compound with the formula (CH2)4S. It consists of a five-membered ring containing four carbon atoms and a sulfur atom. It is the saturated analog of thiophene. It is a volatile, colorless liquid with an intensely unpleasant odor. It is also known as thioph''a''ne, thiolane or THT. ==Synthesis and reactions== It is prepared by the reaction of tetrahydrofuran with hydrogen sulfide. This vapor-phase reaction is catalyzed by alumina and other heterogenous acid catalysts.〔Bernard Loev and John T. Massengale, U. S. Patent 2,899,444, "Synthesis of Tetrahydrothiophene", 8/11/1959〕〔Jonathan Swanston “Thiophene” in Ullmann’s Encyclopedia of Industrial Chemistry Wiley-VCH, Weinheim, 2006. .〕 This compound is a ligand in coordination chemistry, an example being the complex chloro(tetrahydrothiophene)gold(I).〔Rafael Uson, Antonio Laguna, Mariano Laguna, "(Tetrahydrothiophene)Gold(I) or Gold(III) Complexes" Inorganic Syntheses, 1989, Volume 26, pp. 85–91. 〕 Oxidation of THT gives the solvent called sulfolane, a polar solvent with almost no odor. Sulfolane is more conventionally prepared from butadiene. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tetrahydrothiophene」の詳細全文を読む スポンサード リンク
