Organophosphine compound

Organophosphines are organophosphorus compounds with the formula PRnH3−n, where R is an organic substituent. These compounds can be classified according to the value of n: primary phosphines (n = 1), secondary phosphines (n = 2), tertiary phosphines (n = 3). All adopt pyramidal structures. … Zobacz więcej Organophophines are classified according to the number of organic substituents. Primary phosphines Primary (1°) phosphines, with the formula RPH2, are typically prepared by alkylation of phosphine. … Zobacz więcej Coordination chemistry Tertiary phosphines are often used as ligands in coordination chemistry. The binding of phosphines bind to metals, which serve as Zobacz więcej Organophosphines, like phosphine itself, are pyramidal molecules with approximate C3v symmetry. The C–P–C bond angles are approximately 98.6°. The C–P–C bond angles are consistent with the notion that phosphorus predominantly uses the 3p orbitals for … Zobacz więcej • Diphosphines, R2PPR2, R2P(CH2)nPR2 • Phosphine oxide, R3P=O • Phosphorane, PR5, R3P=CR2 Zobacz więcej WitrynaA new polyoxometalate (POM)-based organic–inorganic hybrid Cu-coordination polymer, namely {((Cu(bipy)) 2 (μ-PhPO 3) 2 Cu(bipy)) 2 H(PCuW 11 O 39)·3H 2 O} n …
