Addition of the carbanion of chloromethyl methyl sulfone to aldehydes and ketones proceeds faster than its degradation via the Ramberg–Baecklund reaction. Chlorohydrins and oxiranes produced from aldehydes treated with an excess of base undergo the Ramberg–Baecklund reaction giving allylic alcohols, whereas the reaction of ketones gives the oxiranes.
将氯甲基甲基砜的碳负离子加到醛和酮中的过程要比其通过Ramberg-Baecklund反应的降解快。由用过量碱处理过的醛制得的氯醇和环氧乙烷发生Ramberg-Baecklund反应,生成烯丙基醇,而酮反应生成环氧乙烷。
