The invention discloses a synthesizing method of tetrazole-5-methyl formate, which belongs to the technical field of the chemical industry. The synthesizing method comprises the following step: synthesizing a tetrazole-5-methyl formate product by performing two reactions: an imidization salt forming reaction and a cyclization reaction of methyl oxamate, dimethyl sulfate and sodium azide. The synthesizing method is controlled easily and is easy for realizing industrial production; the finished product tetrazole-5-methyl formate is high in yield and purity; the yield is as high as 85.8-92%, andthe purity is as high as 98.2-99.1%.

Thermal decomposition of a 1:1 mixture of (CH3OCO)2C(N3)2 and (CD3OCO)2C(N3)2 to yield 1-methyl-5-carbomethoxytetrazole-dx proceeds with crossover of the isotope label, indicating an intermolecular pathway for this reaction.A chain mechanism involving tetrazolium nucleophiles is proposed.The thermal decomposition of diazidomalonamide (14) and N,N'-dimethyldiazidomalonamide (16) occurs analogously yielding 5-carbamoyltetrazole (15) and 5-(methylcarbamoyl)tetrazole (17), respectively.In order to test the mechanistic possibility that a tetrazolium intermediate plays a role in these decompositions, lithio-5-carbomethoxytetrazole was added in 10percent molar concentration to dimethyl diazidomalonate (1) in dodecane.A similar experiment was carried out with diazidomalonamide (14).In both cases the reaction occured at lower temperatures, and in each case the same products were observed as those obtained in the normal thermolysis.
