摘要：
2-Alkylidene-3,3-dialkyl-1,4-dithianes and their oxathiane analogues were prepared from 1,2-diketones by a process involving formation of the monodithioacetal, transformation to a tertiary alcohol with organometallic reagents and ultimately 1,2-sulphur migration using methanesulphonyl chloride in pyridine as the activating agent.
