Abstract

Abstract: Ortho-substituted diaryloxide tricarbonylchromium (O) complexes PhOAr-Cr (CO) 3, treated with carbanions Nu−, give, after acid quenching, paradisubstituted complexes NuAr- Cr (CO) 3 via a 1, 3-hydride migration followed by elimination of phenol: the overall sequence of the reaction consists in a regioselective meta substitution of the phenoxy group by the nucleophile.
