Our investigations of the iodine oxidation of divalent sulfur have been extended to include the thiol group.In acetonitrile the rates of iodine oxidation of thiols can be measured at 25.0 deg C by using stopped-flow techniques.The oxidation of the isomeri

Primary alcohols are converted into dialkyl disulfides via heating in situ generated O-alkyl S-difluoro(ethoxycarbonyl)methyl xanthates from ethyl bromodifluoroacetate and potassium xanthates, prepared from primary alcohols and carbon disulfide in the presence of KOH. The reaction mechanism is suggested as an alkyl C[1,3] shift followed by a radical mechanism. This extends to the Chugaev elimination which yields olefins. The current research provides easy access to dialkyl disulfides from commercially available primary alkanols.
AGENT FOR INTRODUCING PROTECTING GROUP FOR HYDROXY GROUP AND/OR MERCAPTO GROUP
-
Paragraph 0058, (2017/11/11)
A novel agent for introducing a protecting group for a hydroxy group and/or a mercapto group that can be introduced and removed under mild conditions is provided. The agent for introducing a protecting group for a hydroxy group and/or mercapto group of a substrate compound having the hydroxy group and/or mercapto group is represented by the following formula (I), wherein A represents a ring structure having 1 to 5 rings in which two carbon atoms of an adjacent benzene ring are included, the ring structure comprises a substituted or unsubstituted five-membered ring or six-membered ring and optionally include a heterocycle; each of R1, R2, R3, and R4 is independently a hydrogen atom or a linear or branched alkyl group having 1 to 5 carbon atoms; and X is a halogen atom or OSO2R5 (R5=an aryl group or an alkyl group).
