2,3-Dimethyl-2,3-dinitrobutane (DMNB) was prepared by oxidative coupling of acetone oxime with H2O2 over the modified TS-1 catalyst. In one-pot operation, the ammoximation of acetone followed by catalytic oxidative coupling over TS-1 produced the DMNB with yield of 43.2%. The operation is simple and safe. The structures of products were identified by 1H NMR and 13C NMR spectra.

Key words: acetone oxime, oxidative coupling, hydrogen peroxide, 2,3-dimethyl-2,3-dinitrobutane, modified TS-1 catalyst
