Abstract. Triphenylphosphine (TPP)-based luminescent compounds are rarely investigated because of the low photoluminescence … Triphenylphosphine (IUPAC name: triphenylphosphane) is a common organophosphorus compound with the formula P(C6H5)3 and often abbreviated to PPh3 or Ph3P. It is widely used in the synthesis of organic and organometallic compounds. PPh3 exists as relatively air stable, colorless crystals … See more Triphenylphosphine can be prepared in the laboratory by treatment of phosphorus trichloride with phenylmagnesium bromide or phenyllithium. The industrial synthesis involves the reaction between phosphorus trichloride See more Oxidation Triphenylphosphine undergoes slow oxidation by air to give triphenylphosphine oxide, … See more Triphenylphosphine binds well to most transition metals, especially those in the middle and late transition metals of groups 7–10. In terms of steric bulk, PPh3 has a Tolman cone angle of 145°, which is intermediate between those of P(C6H11)3 (170°) and P(CH3)3 … See more • Tris(o-tolyl)phosphine • Decyl(triphenyl)phosphonium See more PPh3 is widely used in organic synthesis. The properties that guide its usage are its nucleophilicity and its reducing character.
