μ - nitrido -bis ( triphenylphosphine ) chloride, is a chemical substance having the formula [ ( ( C6H5) 3P) 2N ] Cl, which is often abbreviated as PPNCl. The colorless salt is a source of [ PPN ] - cation, which is used otherwise difficult to crystallize anions. [ PPN ] is a phosphazene.

Production

The representation of PPNCl done in two steps from triphenylphosphine:

The resulting Triphenylphosphandichlorid is occupied in organic chemistry Chlorierungsreazenz present as trigonal bipyramidal molecule in polar solvents as an ion pair, and in non-polar solvents. Further treatment with hydroxylamine in the presence of one equivalent of Ph3P resulted in the replacement of the P -Cl by P = N bonds:

Application

PPN chloride is the most important precursor for further [ PPN ] salts by displacement reactions nitrites, azides and other small inorganic anions can [ PPN ] are obtained as cation. These salts are soluble in polar organic solvents. [ PPN ] salts permit the crystallization of compounds with anions, metal salts thereof, would be unstable in the solid phase.
