The mechanism of the formation of 5-substituted 1H-tetrazoles from organic nitriles and thiocyanates in the presence of NaN3 and ZnCl2 in aliphatic alcohols was studied. The results of this study allowed efficient methods of synthesis of substituted tetrazoles from nitriles, thiocyanates, and isothiocyanates to be proposed.

Addition of 1-substituted tetrazol-5-ones to dimethyl 2-chloroethynylphosphonate occurred regioselectively to form new geminally substituted bis(4-R-5-oxo-4,5-dihydro-1H-tetrazol-1-yl)ethenylphosphonates with 65- 92% yield.

Treatments of organic isothiocyanates (R-NCS) with NaN3 in the presence of pyridine in water at room temperature gave corresponding various organic tetrazole-thiones, [S=CN4(R)] (R = alkyl or aryl). Isolated products are obtained as white or yellow solids in good yields (76-97%). The molecular structure by X-ray diffraction study for one of products shows the proposed formation. In addition, one-pot synthesis of 1- substituted 5-alkyl(or aryl)sulfanyltetrazoles has been demonstrated. Addition of alkyl or aryl halides into the mixture of organic isothiocyanates, NaN3, and pyridine in water at room temperature exclusively formed 1- substituted 5-alkyl(or aryl)sulfanyltetrazoles (S-derivatives) in high yields.

Several 5-thio-substituted tetrazole derivatives were efficiently synthesized by a three-step process. The substituted tetrazol-5-thiol, namely, 1-benzyl-1H-tetrazole-5-thiol (2) was prepared by refluxing commercially available benzyl isothiocyanate (1) w
