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

Conclusions We have used²⁷Al NMR to study disproportionation processes in a series of aryloxy derivatives of alkali-metal aluminum hydrides, MAlH_4–n(OAr^m), and have shown that an increase in steric hindrance in the aryl radical increases the stability of the alkali-metal aluminum hydride aryloxy derivatives.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 865–869, April, 1984.The authors wish to thank A. V. Kisin for making the²⁷Al NMR exposures.
