  Reactivity of neutral nitrogen donors in planar d8 metal complexes. Part 1. The system [1,2-bis(phenylsulfanyl)-ethane]dichloroplatinum(II) with pyridines in methanol. Effect of basicity and steric hindrance

  摘要：

  The kinetics of the forward and reverse steps of the process [Pt(PhSCH2CH2SPh)Cl2]+ am half arrow right over half arrow left [Pt(PhSCH2CH2SPh)(am)Cl]+ + Cl-(am = one of a number of pyridines and other heterocyclic nitrogen bases covering a wide range of basicity) has been studied in methanol at 25-degrees-C. Both forward and reverse reactions obey the usual two-term rate law observed in square-planar substitution. The second-order rate constants for the forward reactions, k2f show only a slight dependence upon the nature of the entering pyridine, and steric hindrance due to the presence of one or two methyl groups in alpha position to the nitrogen markedly decreases the reactivity. The first- and second-order rate constants for the reverse reaction are very sensitive to the basicity of the leaving group and a plot of log k2r against the pK(a) of the conjugate acids of unhindered pyridines is linear with a slope of -0.56. Steric retardation for monosubstituted alpha-methylpyridines is relatively small. The equilibrium constants for these reactions have been determined from the ratio of the rate constants and a plot of log K against the pK(a) of the unhindered pyridines is linear with a slope of 0.58. The results are compared with data from the literature and discussed in terms of the reaction profile.
