Disaster Review Fact Sheet

In chemistry, phosphine-boranes are organophosphorus compounds with the formula R3−nHnPBH3. They are Lewis acid-Lewis base adducts derived from organophosphines (PR3−nHn) and borane (BH3). They are generally colorless or white solids. Since these adducts are air-stable, they represent a protected form of the parent organophosphine.
