A facile synthesis of imidazoles and tetrazoles via [3+1+1] type cyclization of ClCF2COONa is developed. A diverse array of imidazoles and tetrazoles were obtained in decent yields via isocyanide intermediates. Notably, this is the first example of the cycloaddition of in situ generated isocyanides.

1-substituted-1H-tetrazole analogues 4(a–o) were synthesized, which were typically accessed via a facile, solvent-free and green synthetic protocol. The reaction involves expeditious reusable catalyst (SiO2–H3BO3) promoted condensation between a variety of heterocyclic/aromatic amines, sodium azide and triethyl ortho-formate, eliminating the use of an environmentally toxic solvent. This new eco-friendly and sustainable

New tetrazole compounds were synthesized and characterised by NMR and FTIR spectroscopy as well as by single crystal X-ray diffraction. We present in this paper mono- and ditetrazoles, which represent a versatile class of building blocks for the formation of mononuclear iron(H) complexes with monotetrazoles as terminal ligands as well as iron(H) coordination polymers with ditetrazoles as bridging ligands. Especially, the series of alpha,w-bis[tetrazol-1-yl]-alkanes open the field of fascinating supramolecular structures with spin transition properties. (C) 2004 Elsevier B.V. All rights reserved.
