Box 3503, 11120 Belgrade, Serbia and Montenegro (e-mail: [email protected]) (Received 14 May, revised 26 July 2004) Abstract: Rate constants for the reaction of diazodiphenylmethane with isomeric pyridine carboxylic acids were determined in chosen protic and aprotic solvents at 30 °C, using the well known UV spectrophotometric method. The values of the rate constants of the investigated acids in protic solvents were higher than those in aprotic solvents. The second order rate constants were correlated with solvent pa- rameters using the Kamlet-Taft solvatochromic equation in the form: log k =logk0 + sp*+aa + bb. The correlation of the obtained kinetic data were performed by means of multiple linear regression analysis taking appropriate solvent parameters. The signs of the equation coefficients were in agreement with the postulated reaction mechanism. The mode of the influence of the solvent on the reaction rate in all the investigated acids are discussed on the basis of the correlation results. Keywords: pyridine carboxylic acids, diazodiphenylmethane, rate constants, solvent parameters, protic and aprotic solvents. INTRODUCTION The relationship between the structure of carboxylic acids and their reactivity with diazodiphenylmethane (DDM) has been studied by many authors,1,2 with particular regard to the influence of the solvent.
