alkylation of 2,3-dimercapto-1-propanol with alkyl halides leads in good yield to 2,3-bis(alkylthio)-1-propanol and dialkyl sulfide. The reaction of 2,3-bis(alkylthio)-1-propanol with catalytic concentrated sulfuric acid proceeds with rearrangement to give 1,2,3-tris(alkylthio)propane and dialkyl disulfide. The rearrangement reaction takes place through a common intermediate thiaranium intermediate 8.
2,3-二巯基-1-丙醇与烷基卤的烷基烷基化反应可产生2,3-双(烷硫基)-1-丙醇和二烷基硫醚。2,3-双(烷硫基)-1-丙醇与催化浓硫酸的反应进行重排,得到1,2,3-三(烷硫基)丙烷和二烷基二硫化物。重排反应通过普通的中间体th中间体8发生。
