Abstract

Changes which were found to occur in the proton nmr spectrum of benzyltrimethylhydrazine at low temperatures are discussed in terms of hindered rotation about the nitrogen-nitrogen bond and slow nitrogen inversion. It is concluded that, below -130°, inversion of the nitrogen atom bearing the benzyl group is slow on the nmr time scale. The barrier to inversion is calculated to be 6.8 kcal/mol, which is substantially lower than the barriers found for cyclic and bicyclic hydrazines or for group V analogs of hydrazine.
