Abstract

Abstract: Log K, Aff, and TU values for the interaction of several arenediazonium salts with 18-crown-6 were determined in methanol at 25 OC by the calorimetric titration technique. The complex of benzenediazonium cation with 18-crown-6 is enthalpy stabilized with log K= 2.50. Substitution of a methyl group onto the ortho position (s) of benzenediazonium cation results in a total loss of complex stability. Substitution of various groups onto the para ...
