The reaction of fluoro-2,4-dinitrobenzene with the sodium salt of diethyl malonate to form diethyl (2,4-dinitrophenyl)malonate is fast in dimethyl sulfoxide solvent. The stable red color of the reaction solution is due to the anion of the product, although the initially formed unstable intermediate between the substrate and the anion nucleophile is also red and can be observed at times less than 200 ms after mixing.The rate constants for all the steps in the reaction have been measured and the activation parameters for the three processes involved in the nucleophile substitution have been calculated.

13C Fourier-transform N.M.R. has been used to measure the rate of exchange of dimethyl sulfoxide with hexakis(dimethyl sulfoxide)nickel(II) cation. The parameters obtained, kex(25°C)(9.8�4.6) × 103 s-1, ΔH‡ 50�2 kJ mol-1 and ΔS‡ 0�4 J K-1 mol-1, are in excellent agreement with those of the most recent 1H N.M.R. study. The reaction between Ni(Me2SO)62+ and diethyldithiocarbamate (dtc-) gives only Ni(dtc)2. When dtc- is in excess, the rate of formation of Ni(dtc)2 is first order in Ni2+ and dtc-. The ionic-strength and temperature dependences of the second-order rate constants are consistent with the rate-determining formation of an unstable Ni(dtc)+ complex by an ID mechanism.
