Abstract

Both the equilibria shown in the scheme are studied by NMR.

ChemInform Abstract

Both the equilibria shown in the scheme are studied by NMR. Equilibrium constants are measured as a function of pressure (up to 2000 and 1140 bar, respectively) to obtain volumes of reaction which relate to the formation of the "tetrahedral intermediate" of ester hydrolysis. The equilibrium (I)/(II) is studied also as a function of temp. (265-305 K).
