Phosphoranimine
Web(1) Poly (organo)phosphazenes are a family of inorganic molecular hybrid polymers based on a phosphorus–nitrogen backbone substituted with organic side groups which show very differing properties due to the vast array of organic substituents possible. Phosphorylethanolamine or phosphoethanolamine is an ethanolamine derivative that is used to construct two different categories of phospholipids. One category termed a glycerophospholipid and the other a sphingomyelin, or more specifically within the sphingomyelin class, a sphingophospholipid. Phosphorylethanolamine is a polyprotic acid with two pKa values at 5.61 and 10.39.

WebJun 7, 2015 · The phosphoranimine bond is different from the typical Pπ–Pπ bond in classical conjugated polymers. In a phosphoranimine π-bond, the electron on nitrogen is in a 2Pz orbital and the electron on the phosphorus is in a 3 d orbital. The delocalizations of 2Pz-3 d π-bonds are limited in the “islands” of nitrogen and phosphorus atoms. fnpr syndicat russeWebIn addition, phosphoranimine 2 was found to undergo an unexpected oxidative cyclization reaction when treated with the oxygen transfer agent pyridine-N-oxide to yield a P-chlorophosphoryl-ox-3-azoline (18).
