Abstract
Reactions of calix[4]resorcinolarene anions with para-nitrophenyl carboxyla tes in the H2O-DMF medium were studied. The kinetics of this process was me asured by optical spectroscopy and potentiometric titration; the step of fo rmation of acylated calixarene and the subsequent step of its hydrolysis we re detected. Self-association of long-chain calixarenes into micelles decre ases their reactivity with respect to that of the monomers.
