Synthesis of 2-(2-methyltetrazol-5-yl)-2,2-dinitroacetonitrile and its reaction with substituted nitrile N-oxides
A procedure of synthesis of 2-(2-methyltetrazol-5-yl)-2,2-dinitroacetonitrile has been developed and its reaction with substituted nitrile _N_-oxides has been investigated, proceeding by the mechanism of 1,3-dipolar cycloaddition and affording 2-methyl-5-[(1,2,4-oxadiazol-5-yl)(dinitro)methyl]-2_H_-tetrazoles. The latter react with KOH in ethanol forming the potassium salt of 2-methyltetrazol-5-yldinitromethane and substituted 5-hydroxy-1,2,4-oxadiazoles. إقراء المزيد
