Abstract

Abstract: In sharp contrast to alkali-metal enolates, silyl enol ethers and ketene silyl acetals add to aromatic nitro compounds in the presence of a fluoride ion source to give the intermediate dihydroaromatic nitronates, which can be observed by NMR. In situ oxidation of the intermediate with bormine or DDQ yields a-nitroaryl carbonyl compounds in moderate-to- high yields. The reaction is applicable to alkyl-, alkoxy-, and halogen-substituted ...
