WebMar 1, 2011 · These compounds usually contain two oxygen atoms and a larger heteroatom (silicon, phosphorus, sulfur) in addition to carbon. If the heterocycle is suitably substituted with halogen (particularly bromine) containing moities it may function as a vehicle to permit incorporation of flame-retarding units into a polymer or oligomer.

Phosphodiester bond - Wikipedia

A phosphodiesterase is an enzyme that catalyzes the hydrolysis of phosphodiester bonds, for instance a bond in a molecule of cyclic AMP or cyclic GMP. An enzyme that plays an important role in the repair of oxidative DNA damage is the 3'-phosphodiesterase. During the replication of DNA, there is a hole between the phosphates in the backbone left by DN… WebPublikationen bis Ende 2010 - Technische Universität Braunschweig. EN.

WebA phosphoester bond is a bond between the phosphorous atom of a phosphate group and an oxygen atom. Each nucleotide contains one … In organic chemistry, a phosphite ester or organophosphite usually refers to an organophosphorous compound with the formula P(OR)3. They can be considered as esters of an unobserved tautomer phosphorous acid, H3PO3, with the simplest example being trimethylphosphite, P(OCH3)3. Some phosphites … See more From PCl3 Phosphite esters are typically prepared by treating phosphorus trichloride with an alcohol. For alkyl alcohols the displaced chloride ion can attack the phosphite, causing dealkylation … See more Diorganophosphites are derivatives of phosphorus(V) and can be viewed as the di-esters of phosphorous acid ((HO)2P(O)H). They exhibit tautomerism, however, the equilibrium overwhelmingly favours the right-hand (phosphonate-like) form: See more Reactions Phosphites are oxidized to phosphate esters: P(OR)3 + [O] → OP(OR)3 This reaction … See more • Phosphinite P(OR)R2 • Phosphonite P(OR)2R • Ortho ester CH(OR)3 See more WebPhosphitester sind Lewis-Basen und können daher mit vielen Metallionen Komplexe bilden.
