摘要

The unprecedented base-initiated generation of a nitrobenzyne and subsequent addition of preformed arylacetonitrile anion nucleophiles is reported. In all cases, 2-amino-5-nitro-3- benzo [b] furans are obtained as major product with small amounts of 3-arylmethyl-2-cyano- 4-nitrophenols. A mechanism involving ring closure of phenoxide and nitrile groups of the initial aryne-nitrile anion adduct is proposed to account for the formation of the ...
