| Abstract: | Reactions of calix[4]resorcinolarene anions withpara-nitrophenyl carboxylates in the H2O−DMF medium were studied. The kinetics of this process was measured by optical spectroscopy and potentiometric titration; the step of formation of acylated calixarene and the subsequent step of its hydrolysis were detected. Self-association of long-chain calixarenes into micelles decreases their reactivity with respect to that of the monomers. Translated fromIzvestiya Akademii Nauk.
