A study was carried out on the reaction of <I>p</I>-nitrophenyl phosphates with hydroxamate nucleophiles in water in the presence of dialkylammonium bilayer membranes. With ethyl bis(<I>p</I>-nitrophenyl) phosphate, clean second order kinetics was observed for all the hydroxamate nucleophiles, two equivalents of <I>p</I>-nitrophenol being released in most cases. In contrast, a complex kinetics was observed for octadecylbis(<I>p</I>-nitrophenyl)phosphate. The second cleavage process of this long-chain substrate by a long-chain hydroxamate was affected by the fluidity of the matrix membrane, an inflection region being present in the Arrhenius plots near the phase transition temperature(<I>T</I><SUB>c</SUB>) of the 2C<SUB>16</SUB>N<SUP>+</SUP>2C<SUB>1</SUB> membrane. The activation energy was 14 and 21 kcal/mol at temperatures above and below <I>T</I><SUB>c</SUB>, respectively. Similar changes in the activation energy had been observed for decarboxylation and proton abstraction.
