Several azinium-N-(2′-azinyl)aminides are reported. The structure of pyridinium-N-(2′-pyridyl)aminide has been studied, both in solution and in crystalline state, and results have been compared. In non-polar solvents, the aminides present a planar conformation stabilized by an intramolecular hydrogen bond. The reactivity toward electrophiles confirms the structural data, producing either N- or C- substitutions

Differently substituted pyridinium N-heteroarylaminides have been prepared in one step with good yield from N-aminopyridinium iodide and the corresponding heteroaryl chloride. (C) 2003 Elsevier Ltd. All rights reserved.
New approaches to the synthesis of pyridinium N-heteroarylaminides
Different substituted pyridinium N-heteroarylaminides have been prepared in one step from N-aminopyridinium iodide and the Corresponding heteroaryl halide by two alternative routes. The use of Pd catalysis allowed the easy preparation of products from the less reactive haloheterocycles. The use of water as a solvent in conjunction with microwave heating dramatically diminishes the reaction time without having an adverse effect on reaction yields. (C) 2008 Elsevier Ltd.
