Separating triarylboranes, e.g., triphenylborane from diaryl substituted boranes, e.g., diphenyl borinic acid by precipitation wherein the triaryl borane is present in a basic solution as the adduct while avoiding coprecipitation of the boranes by neutralizing the solution to a pH not less than the pH defined by the equation pH=pKn+log (X) and maintaining the ionic strength of the solution so that it is at least about 1 molar upon completion of the neutralization. |
