o-Bromoaryl esters of phosphoricacid react with magnesium to give arene phosphonic acidderivatives via intermediate Grignard compounds. Similar metallation rearrangement processes may be achieved in the case of o-chloroaryl esters if sodium is applied as metal. 2,4-Dibromoaryl esters are attacked by magnesium regiospecifically in o-position.

The dealkylation of phosphaisocoumarin esters was studied under various conditions. An effective way to synthesize phosphaisocoumarin acids was developed via the reaction of phosphaisocoumarin esters with Me3SiBr in chloroform followed by treatment with methanol, or with Me3SiCl and NaI in acetonitrile followed by hydrolysis, under mild conditions in good to excellent yields.
在不同条件下研究了磷酸异香豆素酯的脱烷基化。通过磷酸异香豆素酯与 Me3SiBr 在氯仿中反应,然后用甲醇处理,或在乙腈中与 Me3SiCl 和 NaI 反应,然后水解,开发了一种合成磷酸异香豆素酸的有效方法,在温和条件下具有良好至优异的产率。
