✦ Synopsis
180]-Chlorocarbonylsulfenyl chloride with an isotopic purity of 92% was prepared in three steps starting with the [180]-hydrolysis of 2-ethyl-l,3-dioxolane to [' 80]-propanal, which was then converted to [180]-g-1 -methylpropyl ?-methyl dithiocarbonate, which was then chlorinated to give the title compound.
Distilled yields for the three steps were 57%, 49%, and 40% respectively.
