    Abstract: Preparation of triarylboranes, e.g. triphenylborane by reacting an alkali metal, e.g. sodium; an organohalide, e.g. chlorobenzene and an orthoborate ester, e.g. triisopropylorthoborate in an inert organic solvent, recovering the borane by contacting the reaction product with water while maintaining the ratio of borane to hydrolysis products (e.g. borinic acid) at at least 13/1, distilling volatiles from the aqueous mixture and contacting the resultant material with acid to a pH not less than about 6 to form the borane.
