Complexation of arylboronates with nitrogen-containing bases

Abstract

Complex formation between a number of arylboronates and nitrogenous bases has been studied using different physical techniques. The results of quantitative measurements obtained from 1H and 13C n.m.r. spectroscopy, calorimetry, and polarimetry have been compared, and are in close agreement with each other. In all cases, two unknown variables have been determined by carrying out the experiments with varying concentrations of the esters and bases and treatment of the data thus generated by iterative procedures.
