摘要

The usual method of preparation of phosphonic acids, RPO(0H)z and R2POH, involves the prepa- ration of the corresponding halophosphines by the Friedel-Crafts reaction of the corresponding hy- drocarbon with phosphorus trichloride, followed by oxidation and hydrolysis. Generally, the prepa- ration of the halophosphines is quite unsatisfac- tory because of meager yields. At the same time, the odor and the vapor toxicity of the halophos- phines frequently make them ...
