Abstract: The results of a kinetic study have shown that the reactivity of monomeric forms of amphiphilic tetra- ([H₄L]^4–) and octa- ([L]^8–) anions of calyx[4]resorcinolarenes (H₈L) towards p-nitrophenyl esters of tetracoordinated phosphorus acids in aqueous dimethylformamide (50 vol.% of DMF) is determined by the nucleophilic centres of the anions, whereas an increase in the concentration of H₈L inhibits the process, which is due to the formation of aggregates.
