Versuchsvorschrift

116 g of 1-methyl-1-oxophospholine and 6 g of tert.-butyl perpivalate in dibutyl phthalate are added dropwise with stirring under an oxygen-free atmosphere to 234 g of dimethyl phosphine oxide. The reaction temperature is 75° to 80° C. The starting materials are then distilled off. The residue consists of 185 g of 1-methyl-1-oxophospholanyl dimethyl phosphine oxide.
