Abstract: | As an alternative to volumetric analysis, 11B NMR spectroscopy can be used to determine the hydride concentration and the relative amount of different active hydride
species in mixtures of alkyldiboranes(6) (alkyl = Et, Pr). Inorganic selenium(IV) compounds react with propyldiboranes(6)
at first to give elemental selenium (hydride number HN = 4) and after prolonged heating at 130 °C to selenides (HN = 6). In
contrast, tellurium(IV) and tellurium(VI) compounds are reduced only to elemental tellurium.
