摘要:
Reaction of 2-[(organylthio)methyl]oxiranes with acetic anhydride gives a mixture of 3-(organylthio)-1,2-diacetoxypropane and 2-(organylthio)-1,3-diacetoxypropane, and with acetyl chloride a mixture of 2-chloro-3-(organylthio)-1-acetoxypropane and 3-chloro-2-(organylthio)-1-acetoxypropane. In both cases, the ratio of the isomers depends on the nature of the organylthio group and on the nature of the electrophile.
