Cw. Ong et al., NOVEL REARRANGEMENTS OF 2,3-DIMERCAPTO-1-PROPANOL DERIVATIVES - FORMATION OF DIALKYL SULFIDE, DIALKYL DISULFIDE, AND 1,2,3-TRIS(ALKYLTHIO) PROPANE, Journal of organic chemistry, 61(23), 1996, pp. 8244-8247
The base alkylation of 2,3-dimercapto-1-propanol with alkyl halides le
ads in good yield to 2,3-bis(alkylthio)-1-propanol and dialkyl sulfide
. The reaction of 2,3-bis(alkylthio)-1-propanol with catalytic concent
rated sulfuric acid proceeds with rearrangement to give 1,2,3-tris(alk
ylthio)propane and dialkyl disulfide. The rearrangement reaction takes
place through a common intermediate thiaranium intermediate 8.
