Effect of structural preorganization on the reactivity of carbazoylmethyl derivatives of pyrogallol and calix[4]pyrogallol

“…18 This study showed that the high extraction ability of these compounds com pared to that of their structural unit, namely, 4 tert bu tylphenoxyacetylhydrazide, is caused by the preorganiza tion of the hydrazide groups on the calixarene platform resulting in the positive cooperative effect in binding of metal ions. An important influence of the cooperative effect of the functional groups on the catalytic properties was observed 26 for the supramolecular models of enzymes.…”
