The existence of monomeric metaphosphate in hydroxylic solvent: a positional isotope exchange study
Abstract
The phosphoryl transfer reactions of adenosine 5′-[α,β-18O]diphosphate trianion in acetonitrile, acetonitrile–t-butyl alcohol, and neat t-butyl alcohol are all accompained by closely similar bridge-to-non-bridge scrambling in the reisolated starting material; the simplest interpretation involves a monomeric metaphosphate intermediate even in the presence of hydroxylic solvent.
