has been developed for oxidative SNH alkyl carbamoyl amination of 3-nitropyridine in anhydrous DMSO. When anions of alkyl- and 1,1-dialkylureas were used as nucleophiles, an unusual formation of a mixture consisting of 1-alkyl(1,1-dialkyl)-3-(5-nitropyridin-2-yl)ureas and their nitroso analogs occurred, which was the first such observation with 3-nitropyridine. Only the nitro products formed in the
的方法已被开发用于氧化小号Ñ ħ烷基氨基甲酰基胺化在无水DMSO -3-硝基吡啶。当烷基-和1,1-二烷基脲的阴离子用作亲核试剂时,由1-烷基(1,1-二烷基)-3-(5-硝基吡啶-2-基)脲及其亚硝基组成的混合物会异常形成出现类似物,这是对3-硝基吡啶的首次观察。在硝基苯存在下仅形成硝基产物。另外,基于合成的化合物获得了一系列的N-氧化物。
