The reaction of t-butyllithium with representative trialkylboranes possessing widely differing steric requirements was examined. This reaction occurs rapidly in ether solvents, even at −78°C, with formation of the corresponding lithium trialkylborohydride in quantitative yield. This synthesis is highly general, accomodating even strongly hindered trialkylboranes such as tris(trans-2-methylcyclopentyl)borane

those with exceptionally large steric requirements, react readily with toluene solutions of sodium diethyldihydroaluminate in the presece of 1,4-diazabicyclo[2.2.2]octane, resulting in a convenient and generalpreparation of sodium trialkylhydroborates.
