Facile Elimination of Ethanethiol in the Reaction of α-Hydroxy-β-bis(ethylthio)acetals with Copper(I) Chloride in Dimethylformamide
Bis(ethylthio)acetals possessing a hydroxy group in the α-position eliminate, upon reaction with copper(I) chloride in dimethylformamide, cleanly and quantitatively one molecule of ethanethiol with the formation of substituted ethyl vinyl sulfides.
