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, removing alcohol from the aqueous mixture and contacting the resultant material with acid to a pH not less than about 6 to form the borane.
