Data on methods for the synthesis of monocyclic and polynuclear NH-unsubstituted tetrazoles are reviewed.

The effect of 5-substituted tetrazoles on the corrosion resistance of ferrous and nonferrous metals in aqueous solutions of Na2SO4, simulating a possible electrolyte of atmospheric corrosion, is studied potentiodynamically. Corrosion inhibition is caused by the formation of adsorbed films of the surface metal-tetrazole complexes.

The kinetics of the reaction of 5-phenyltetrazole triethylammonium salt with methyl vinyl ketone in acetonitrile and DMFA were studied. At a concentration of approx. 2.5 x 10/sup -1/ M the 5-phenyltetrazole triethylammonium salt is associated, and an intimate ion pair, formed with participation of a hydrogen bond, enters into reaction with the methyl vinyl ketone. The controlling stage is the formation of the anionic intermediate, the subsequent protonation of which leads to the final reaction products. The PMR spectra were recorded on a Perkin-Elmer R-12 spectrometer at 60 MHz in acetone-d/sub 6/ with HMDS as internal standard.

AbstractBenzonitrile (I) reacts with ammonium, alkyl‐, dialkyl‐, and trialkyl ammonium azides (II) to give 5‐phenyltetrazole (III).
