Nitramines and nitramides. Part XIV. Application of nuclear magnetic resonance spectra to the problem of isomerism in ON-dialkylnitramines, with some observations on ON-dialkylnitrosohydroxylamines

Abstract

¹ H Nuclear magnetic resonance spectra provide evidence for the existence of ON-dialkylnitramines (RH:NO₂R′) in geometrically isomeric forms, which do not appear to be readily interconvertible. The spectra of some isomeric dialkyl nitrosohydroxylamines [RN(NO)OR′ and RN(O):NOR′] suggest for the structure RN(NO)OR′ an easier interconversion of conformers than is observed in N-nitrosodialkylamines. No signs of rotational isomerism were observed at 35° in the alkoxyurethanes which were prepared as intermediates.
