Abstract
The anions (1) and (2) have been synthesized by the reaction of benzimidazole with tetracyano-ethylene. They have been characterized by X-ray crystallography and 13C NMR spectroscopy. The molecular structures of their tetraphenylarsonium salts have been determined. The charge delocalization and mechanism of formation are discussed.File in questo prodotto:
