Treatment of methyl 2-chloro-2-(methylthio)acetate, 1-chloro-1-(methylthio)propan-2-one, chloro(methylthio)methyl phenyl ketone, or 2-chloro-2-(methylthio)acetonitrile with 1,3-dienes in the presence of stannic chloride followed by addition of triethylamine gave 1-acyl- or 1-cyano-1-(methylthio)-2-vinylcyclopropanes.A mechanistic interpretation of this reaction is presented.Thermal behaviour of the vinylcyclopropanes is also described.
