27Al NMR study of disproportionation of aryloxy derivatives of alkali-metal aluminum hydrides in tetrahydrofuran

We have used27Al NMR to study disproportionation processes in a series of aryloxy derivatives of alkali-metal aluminum hydrides, MAlH4−n(OArm), and have shown that an increase in steric hindrance in the aryl radical increases the stability of the alkali-metal aluminum hydride aryloxy derivatives.
