The 1:1 phenylhydrazine-borane adduct, obtained from phenylhydrazine and sodium borohydride in acidic solution, was investigated by IR, NMR spectroscopy, and MS spectrometry.

Abstract
The 1:1 phenylhydrazine-borane adduct, obtained from phenylhydrazine and sodium borohydride in acidic solution, was investigated by IR, NMR spectroscopy, and MS spectrometry. Ab initio MO calculations indicated the isomer in which the boron center is attached to the primary amino group as the more stable. This forecast was confirmed by solution-state 1H, 11B, 13C, and 1N NMR spectroscopy, in agreement with the molecular structure in the solid state determined by X-ray analysis.File in questo prodotto:
