In chemistry, a phosphide is a compound containing the P 3− ion or its equivalent. Many different phosphides are known, with widely differing structures. [1] Most commonly encountered on the binary phosphides, i.e. those materials consisting only of phosphorus and a less electronegative element.
Sodium phosphide is the inorganic compound with the formula Na 3 P. It is a black solid. It is often described as Na + salt of the P 3− anion. [2] Na 3 P is a source of the highly reactive phosphide anion.
Triphosphorus pentanitride is an inorganic compound with the chemical formula P 3 N 5. Containing only phosphorus and nitrogen, this material is classified as a binary nitride. While it has been investigated for various applications this has not led to any significant industrial uses.
It may be formed by reaction of the elements, [1] but it is more commonly prepared by carbothermal reduction of calcium phosphate: [2] Ca 3 (PO 4) 2 + 8 C → Ca 3 P 2 + 8 CO. This is also the way how it was accidentally discovered by Smithson Tennant in 1791 while verifying the composition of carbon dioxide proposed by Antoine Lavoisier by reducing calcium carbonate with phosphorus.
In 1988, Lewis C. Cantley published a paper describing the discovery of a novel type of phosphoinositide kinase with the unprecedented ability to phosphorylate the 3' position of the inositol ring resulting in the formation of phosphatidylinositol-3-phosphate (PI3P). [1]
Names Other names Tristrontium diphosphide. Identifiers ... Strontium phosphide is an inorganic compound of strontium and phosphorus with the chemical formula Sr 3 P ...
Lithium phosphide is an inorganic compound of lithium and phosphorus with the chemical formula Li 3 P. This dark colored compound is formally the lithium salt of phosphine, consisting of lithium cations Li + and phosphide anions P 3−. It is hazardous to handle because of its high reactivity toward air. [1]
Phosphorus triiodide is commonly used in the laboratory for the conversion of primary or secondary alcohols to alkyl iodides. [4] The alcohol is frequently used as the solvent, on top of being the reactant.
