摘要

Cyclohexanone reacts with sulfuryl chloride in sulfur dioxide, ether, tetrahydrofuran, dioxane, and tetraglyme to give mixtures of mono-and dichlorocyclohexanones. However, when the reaction was carried out in sulfur dioxide solution containing a slight excess of methanol, only monochlorocyclohexanone was obtained in high yield. Almost as good selectivities are obtained in methylene chloride solution in the presence of methanol. A ...
