Ninhydrin has been found to form a I I complex with C u ( l l ) complexes of asparagine and serine The kinetics of the complexation reaction has been studied spectrophotometrically in acetate buffer. The effect of the [ninhydrinl, pH, and temperature on the reaction rate of the reaction was studied.
The pressure-jump method has been used to determine the rate constants for the formation and dissociation of nickel(I1) and cobalt(I1) complexes with cinchomeronate in aqueous solution at zero ionic strength. The forward and reverse rate constants obtained are k, = 2.27 x lo6 M-' s-' and k, = 3.81 x
The reaction of Pd(Me,en)Cl, (Me,en =N,N,iV',N'-tetramethylethylenediamine) with inosine and 5'-inosine monophosphate was studied as a function of chloride concentration and pH. Evidence for the formation of a 1:l complex with these nucleophiles is presented, and the kinetic data indicate that Pd(Me
