    (PDNPTOC), and O-ethyl 2,4-dinitrophenyl dithiocarbonate (EDNPDTC) are studied kinetically in water, at 25.0 degrees C and an ionic strength of 0.2 M (KCl). All reactions show pseudo-first-order kinetics under an excess of phenol over the substrate, and are first order in phenoxide anion. The reactions of EDNPDTC show a linear Bronsted-type plot of slope beta = 0.67, suggesting a concerted mechanism. On the

    isobasic pyridines. Comparison of the Brönsted-type plots for the dinitro and trinitro derivatives obtained in this work with those for the pyridinolysis of S-(2,4-dinitrophenyl) and S-(2,4,6-trinitrophenyl) O-ethyl thiocarbonates indicates that substitution of S(-) by O(-) in T(+/-) increases the amine/ArS(-) nucleofugality ratio from T(+/-).

  • Structure-reactivity relationships in the aminolysis of O-ethyl S-aryl dithiocarbonates in aqueous solution
    作者:Enrique A. Castro、Maria Cubillos、Fernando Ibanez、Inge Moraga、Jose G. Santos

    日期:1993.9
    The reactions of O-ethyl S-(X-phenyl) dithiocarbonates (X = p-Cl, p-Me, and p-MeO) with a series of secondary alicyclic amines and those of the same substrates and analogous derivatives (X = H, p-NO2, and 2,4-(NO2)2) with pyrrolidine are subjected to a kinetic study in water, 25.0-degrees-C, ionic strength 0.2 M (KCl). The reactions of piperidine and pyrrolidine show second-order kinetics (first order in amine) with the formation of a zwitterionic tetrahedral intermediate (T+/-) as the rate-determining step, The reactions of the other amines exhibit orders in amine different from one, compatible with the presence of an anionic intermediate (T-), resulting from a kinetically important proton transfer from T+/- to the amine. The rate of this proton transfer is faster than that of expulsion of arylthiolate from T+/- (k2) as evidenced by the estimation of these rate coefficients. The rate constants for formation of T+/- (k1) are obtained experimentally, and those for amine expulsion from T+/- (k-1) are estimated. Equations for k1 and k-1 are derived as functions of the basicity of the amine and leaving (aryl thiolate) groups. Comparison of the k-1 and k2 values found in the present reactions with those obtained in the aminolysis of aryl dithioacetates shows that substitution of Me by EtO as the ''acyl'' group of the zwitterionic tetrahedral intermediate destabilizes this species.
  • Structure-reactivity correlation in the reactions of pyrrolidine with O-ethyl S-aryl dithiocarbonates in aqueous ethanol
    作者:Enrique A. Castro、Mauricio Cabrera、Jose G. Santos
    DOI:10.1002/(sici)1097-4601(1997)29:2<113::aid-kin4>3.0.co;2-x
    日期:——
    The reactions of pyrrolidine with O-ethyl S-(X-phenyl) dithiocarbonates (X = 4-methyl, 4-methoxy, H, 4-chloro, 4-nitro, 2,4-dinitro, and 2,4,6-trinitro) are subjected to a kinetic study in 44 wt% aqueous ethanol, 25.0 degrees C, and ionic strength 0.2 M (maintained with KCl). Pseudo-first-order kinetics are found under amine excess. Linear plots of the pseudo-first-order rate coefficient against concentration of free-base pyrrolidine are obtained for all the reactions, the nucleophilic rate coefficient (it,) being the slope of such plots. The Bronsted-type plot (log k(N) vs. pK(a) for the leaving group) is linear with slope beta(lg) = -0.2, which is consistent with a mechanism through a tetrahedral intermediate (T-+/-) where its formation is rate determining. The beta(lg) Value is very similar to that found in the same reactions in water. There is a great difference in the mechanism of the reactions of O-ethyl S-phenyl dithiocarbonate with pyrrolidine (order one in amine) and piperidine (complex order in amine) in aqueous ethanol, and this is attributed to a greater nucleofugality from T-+/- of piperidine rather than pyrrolidine.
