Abstract

Abstract Phosphinous acid o-bromoaryl esters or phosphorus acid o-haloaryl ester diamides react with sodium under mild conditions to give the corresponding sodium aryls which undergo rapid 1, 3-carbanionic rearrangements to give o-phosphinophenolates. These may be worked up to the free phenoles or silylated by treatment with Me 3 SiCl.
