Allenic sulfones are directly prepared by the Horner-Wittig reaction of diethyl methyl(or aryl)sulfonylmethylphosphonate anions with ketenes. The method affords excellent to moderate yields respectively with phenylethyl and diphenylketene, the latter being more sensitive to basic media.
烯丙基磺醚是通过二乙基甲基(或芳基)磺酰基甲基磷酸酯阴离子与酮烯的霍纳-威蒂格反应直接制备的。该方法在苯乙烯和二苯酮的反应中分别获得了优良到中等的产率,后者对碱性介质更为敏感。
