The synthesis of cyanamides and tetrazoles from isothiocyanates through tandem reaction using cobalt catalyst has been demonstrated. In the case of tetrazole preparation, the reaction involved addition/desulfurization/nucleophilic addition/electrocyclization, whereas aromatic cyanamides were constructed from isothiocyanates through addition/desulfurization. Cheap cobalt sulfate was used for the synthesis
versatile synthetic methodology for the construction of tetrazoles and guanidines in the presence of an eco-friendly, inexpensive, easily available iron reagent. Aromatic thioureas with electron-donating substituents produced their respective target products in quantitative yield. In contrast, when electron-withdrawing substituted aromatic thioureas were used, the expected products were obtained in reduced

the antiviral activity of thiopyrano[2,3-b]quinolines is notably affected by both the nature and position of the substituent within the tetrazole ring, as well as the substituent within the benzene moiety of quinoline. These findings contribute to the further search for new antiviral agents against influenza A viruses among derivatives of thiopyrano[2,3-b]quinoline.
nitrogen content and positive heat of formation. The thermal decompositionmechanism of 1-Butyl-3-methyl-imidazolium-5-aminotetrazolate (BMIMAT) has been studied by use of Py-GC–MS and B3LYP/6–311 + G(d,p) level of density functional theory (DFT). The mechanism of decomposition observed is a bimolecular nucleophilic substitution (SN2) reaction. The kinetics of decomposition is studied using Kissinger
