143ChemInform Abstract The preparations of the (5-tetrazolyl)tri-, -di-and -mononitromethanes and their tetrazolyl-1-and tetrazolyl-2-methyl derivatives -i.e. the compounds (II), (III), (V), (VII), (IX) and (XIX) -are described. The reactions of the derivatives (VII), (IX) and (XIX) with diazomethane according to method A) proceed via methylation of the nitrogen atoms of the heterocycle or the oxygen atoms of the nitro groups to afford the corresponding products. No methylation of the exocyclic carbon atom is observed in any of the reactions. The mixture of the isomeric nitronic acid methyl esters (XII) and (XIII) spontaneously yields the bis(5-tetrazolyl)oxadiazole derivative (XV).
