WebThe parent compound of the phosphines is PH 3, called phosphine in the US and British Commonwealth, but phosphane elsewhere. [7] Replacement of one or more hydrogen centers by an organic substituents (alkyl, aryl), gives PH 3−x R x, an organophosphine, generally referred to as phosphines. WebIn chemistry, phosphine-boranes are organophosphorus compounds with the formula R 3−n H n PBH 3. They are Lewis acid-Lewis base adducts derived from organophosphines (PR 3−n H n) and borane (BH 3 ). They are generally colorless or white solids. Since these adducts are air-stable, they represent a protected form of the parent organophosphine.
