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]-2H-tetrazoles. The latter react with KOH in ethanol forming the potassium salt of 2-methyltetrazol-5-yldinitromethane
的合成的过程2-(2-甲基四唑-5-基)-2,2-二dinitroacetonitrile已经开发和其与腈取代反应Ñ -oxides已经研究了,通过1,3-偶极环加成的机构出发,得到2-甲基-5-[(1,2,4-恶二唑-5-基)(二硝基)甲基] -2 H-四唑。后者与KOH在乙醇中反应,形成2-甲基四唑-5-基二硝基甲烷和取代的5-羟基-1,2,4-恶二唑的钾盐。
