Abstract
The results of a kinetic study have shown that the reactivity of monom eric forms of amphiphilic tetra-([H4L](4-)) and octa-([L](8-)) anions of calix[4]resorcinolarenes (H8L) towards p-nitrophenyl esters of tetr acoordinated phosphorus acids in aqueous dimethylformamide (50 vol.% o f DMF) is determined by the nucleophilic centres of the anions, wherea s an increase in the concentration of H8L inhibits the process, which is due to the formation of aggregates.
