|Section2= |Section3= }} 1,2-Benzenedithiol is the organosulfur compound with the formula C6H4(SH)2. This colourless viscous liquid consists of a benzene ring with a pair of adjacent thiol groups. The conjugate base of this diprotic compound serves as chelating agent in coordination chemistry and a building block for the synthesis of other organosulfur compounds.〔Karlin, K. D.; Stiefel, E. I., Eds. “Progress in Inorganic Chemistry, Dithiolene Chemistry: Synthesis, Properties, and Applications” Wiley-Interscience: New York, 2003. ISBN 0-471-37829-1〕 ==Synthesis== The compound is prepared by ortho-lithiation of benzenethiol using butyl lithium (BuLi) followed by sulfidation: :C6H5SH + 2 BuLi → C6H4SLi-2-Li + 2 BuH :C6H4SLi-2-Li + S → C6H4(SLi)2 :C6H4(SLi)2 + 2 HCl → C6H4(SH)2 + 2 LiCl The compound was first prepared from 2-aminobenzenethiol via diazotization. Alternatively, it forms from 1,2-dibromobenzene. 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「1,2-Benzenedithiol」の詳細全文を読む スポンサード リンク
