A Facile High-Yield Synthesis and Purification ofTetrabutylammonium Tetrabutylborate
Journal of Organic Chemistry
The compound tetrabutylammonium tetrabutylborate has a long history of use in several areas of chemistry,1 and particularly in studies of the thermodynamics of ion solvation.2 Until very recently this compound was commercially available, albeit from a single source. Presently there are no commercial sources for tetrabutylammonium tetrabutylborate. Our search of the literature turned up only a single, low-yield (<10%) synthesis for the compound.3 In addition difficulties in its purification have been reported, and literature melting points for the pure compound range from 109.5 °C4 to 110.6−112.0 °C.3
