Popis:	The kinetics of formation of the 1:1 complexes of some dialkyl-2,2′-bipyridyl-5,5′-dicarboxylates with the ion of Ni(II) have been determined by the stopped-flow spectrophotometric method. Second-order formation rate constants have been correlated with the Taft modification of the Hammett equation. A linear regression has been found (P = 0.95 confidence) with the following characteristics: slope = -0.6 ± 0.1; intercept = 1.32 ± 0.02 (log k0). An inductive effect of the alkyl groups upon the reaction of the complexation is proposed.
