DOI: dx.doi.org/10.19261/cjm.2012.07(2).04

Graphical Abstract: A simple and efficient method for preparation of 5-aryloxy tetrazoles (3a-h) from arylcyanates (1a-h) with using ZnCl₂/AlCl₃/silica (ZAS) as an effective heterogeneous catalyst in solvent free are described with excellent yields and high purity. The rate of product formation was enhanced by introduction of electron donating substituents. The ¹H NMR and chemical shifts and multiplicities are also discussed.

Graphical Abstract: Directed synthesis of dianiline- (DAnH2) and disulfanilamideglyoximes (DSamH2) has been accomplished by condensation of dichloroglyoxime with aniline or sulfanilamide in 1:2 molar ratio, as well as their corresponding Co(III), Ni(II) and Cu(II) coordinative compounds. Composition, structure and some properties of dioximes and complexes have been established by using elemental analysis, UV-Vis, IR and NMRspectroscopies. Dioxime coordination at the central atom and structure of complexes depends on pH of reaction medium: at pH=5-6 - bis-dioximates, whilst at pH=2 – tris-dioximines are obtained.
