Abstract

Trialkylboranes in tetrahydrofuran (THF) or diethyl ether (EE) solutions, including those with exceptionally large steric requirements, react readily with toluene solutions of sodium diethyldihydroaluminate inthe presence of 1,4-diaza-bicyclo[2.2.2]octane (DABCO) to yield the corresponding sodium trialkylborohydrides and diethylaluminum hydride. The diethyl-aluminum hydride precipitates from solution as its DABCO adduct, with the use of EE as solvent facilitating the separation. Thisreaction constitutes a convenient, general method for preparing sodium trialkylborohydrides.
