A number of carboxy substituted aryl phosphates have been prepared and subjected to anionic rearrangement conditions to provide the corresponding phenolic phosphonates. Steric effects of the phosphate ester group and the electronic effects of the aryl carboxy group can limit the scope of the rearrangement.
我们制备了一些羧基取代的芳基
膦酸盐,并在阴离子重排条件下生成了相应的
酚醛
膦酸盐。
磷酸酯基团的立体效应和芳基羧基的电子效应会限制重排的范围。
