For the role of monomeric metaphosphate and the nature of the transition states in the alcoholysis of phosphoric monoesters to be examined, phenyl <(R)-16O,17O,18O>phosphate and 2,4-dinitrophenyl <(R)-16O,17O,18O>phosphate have been synthesized and the stereochemical course of the methanolysis of phenyl phosphate monoanion and of dinitrophenyl phosphate dianion has been evaluated. <(R)-16O,17O,18O>Phosphocreatine has also been synthesized and the stereochemical course of the methanolysis of this molecule determined.In each case, complete inversion of configuration at phosphorus is observed.It is clear that metaphosphate, if it exists as a true intermediate in these reactions in protic solvent, does not leave the solvent cage in which it is generated.Indeed, product formation occurs more rapidly than rotation of the putative metaphosphate intermediate.These displacements must therefore occur by preassociative mechanisms in which there may be some assistance from the incoming nucleophile.The present results do not allow a distinction to be made between a “preassociative concerted” path (that is, an SN2-like displacement via a very loose transition state) and a “preassociative stepwise” path via a metaphosphate intermediate of very short lifetime.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Related Products of 24621-61-2. In my other articles, you can also check out more blogs about Related Products of 24621-61-2
