## Abstract Nitronate anions derived from primary and secondary nitroal‐kanes undergo cross‐coupling reactions with diethyl alkylmalonate anions in alcohol/DMF solution when treated with silver nitrate. A catalytic amount of chloride ions is necessary to promote selective reaction.
Halo carbanions / Vicarious Nucleophilic Substitution (VNS) / Annulation / Quinoxalines / Naphthyridines Carbanions of a-haloalkyl aryl sulfones, sulfonates, and sulfonamides react with bicyclic heteroaromatic compounds (qui- noxalines, naphthyridines, and 5-azaquinoxalines) according to two general
