Versuchsvorschrift

To a solution of 11.6 g (0.2 mol) of allyl alcohol and 18.1 g (0.1 mol) of 2-chloroethane phosphonic acid dichloride in 150 ml of absolute ether are added dropwise with stirring 15.8 g (0.2 mol) of pyridine. When the exothermic reaction is complete, stirring is continued for 15 hours at 40° after which the precipitated hydrochloride is removed by filtration and the ethereal filtrate washed to neutrality with water, dried and then evaporated. It is further dried by rotation under high vacuum over a period of 2 hours at 25°. A yellowish oil is obtained having the following characterisation data: Analysis: C8H14ClO3P Mol weight: 224.6
