It is a colorless, pyrophoric solid that is commercially available in toluene solution, unlike the related LiBH(C2H5)3 which is typically sold as a THF solution.[1] It is commonly used for the reductive activation of homogeneous catalysts, converting metal halides to hydrides. Sodium triethylborohydride has been prepared by treating a hot toluene slurry of sodium hydride with triethylborane.[2] The trimethylborohydride analogue, which is assumed to be structurally similar to the triethylborohydride, adopts a tetrameric structure in toluene solution.[3] References1. ^{{Cite web|url=http://www.callery.com/products/boranes|title=Callery Borane Products {{!}} Callery.com {{!}} Callery|date=2017-03-05|website=Callery|language=en-us|access-date=2017-03-05}} 2. ^Binger, P.; Köster, R., "Sodium triethylhydroborate, sodium tetraethylborate, and sodium triethyl-1-propynylborate", Inorg.
