The rates of keto-enol tautomerism of pentane-2,4-dione (acetylacetone) have been measured spectrophotometrically in reversed micellar systems of dodecylammonium propionate (DAP) and dodecylammonium butyrate (DAB) at pressures up to 98.1 MPa.The rates were enhanced by pressure and surfactants, especially at concentrations above the 'operational' critical micelle concentration.The activation volumes of the reaction (ΔV++) in various systems have been determined and used to estimate the polarity of the microscopic reaction environment.On the basis of the kinetic and thermodynamic data obtained, the formation of reversed micelles as a reaction field is discussed.
The Reactivity of p-Nitrophenyl Esters with Surfactants in Nonaqueous Solvents. III. The Effect of Altering the Head-Groups of Alkylammonium Carboxylates Dissolved in Benzene

The rate of decomposition of p-nitrophenyl acetate, pnpa, has been measured in benzene solutions of a series of alkylammonium propionates, CH3(CH2)nNH3+ -O2CCH2CH3 (where n = 3,5,7,9 or 11), and a series of dodecylammonium carboxylat
