摘要
The products formed in the course of the reduction of 2,3-dimethyl-2,3-dinitrobutane to 2,3-dihydroxylamino-2,3-dimethylbutane in a Zn/NH4Cl/EtOH-H2O system have been investigated. An improved synthesis of 2,3-dihydroxylamino-2,3-dimethylbutane (and its monosulphate salt) - the key precursor of Ullman's nitroxides - in a Zn/NH4Cl/THF-H2O system is proposed.
