the rate of hydrolysis of five-membered cyclicphosphateesters compared to their acyclic analogues is purely enthalpic and arises at least partially from destabilization of the four-coordinate cyclic reactant compared to the acyclic analogue, assuming that both react with hydroxide through unstrained five-coordinate transition states. Calorimetric analysis of the hydrolysis of cyclic and acyclic phosphates
