Abstract

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.

Key Words:

hydroxylamine derivatives
nitroxides
