Explore: Phosphines

hydrides of the form PnHn+2, such as triphosphane. Phosphine (PH3) is the smallest of the phosphines and the smallest of the phosphanes. Philippe Gengembre

classified according to the value of n: primary phosphines (n = 1), secondary phosphines (n = 2), tertiary phosphines (n = 3). All adopt pyramidal structures

P-Chiral phosphines are organophosphorus compounds of the formula PRR′R″, where R, R′, R″ = H, alkyl, aryl, etc. They are a subset of chiral phosphines, a broader

Many metal phosphine complexes are prepared by reactions of metal halides with preformed phosphines. For example, treatment of a suspension

tertiary phosphine sulfide is triphenylphosphine sulfide. Phosphine sulfides are sometimes intermediates in the synthesis of tertiary phosphines. Phosphine sulfides

phosphonium salts. Phosphines are nucleophilic catalysts in organic synthesis, e.g. the Rauhut–Currier reaction and Baylis-Hillman reaction. Phosphines are reducing

Phosphines accept electron density from metal p or d orbitals into combinations of P–C σ* antibonding orbitals that have π symmetry. When phosphines bond

inversion applies to many types of molecules, including carbanions, amines, phosphines, arsines, stibines, and sulfoxides. The identity of the inverting atom

September 2020, research was published that reported the presence of phosphine in the planet's atmosphere, a potential biosignature. However, doubts

encountered phosphine oxides. With the formula R3PO, they are tetrahedral compounds. They are usually prepared by oxidation of tertiary phosphines. The P-O
