Kinetic Behaviour

Rate constants and associated activation parameters for the reaction of galvinoxyl with substituted phenols were obtained in carbon tetrachloride and in cyclohexane-dioxan binary mixtures. Substantial isotope effects were observed for O-deuterated phenols. The rate constants are correlated with σ+ values. These findings are discussed by considering the polar contribution of substituents to the stabilization of the transition states. In the mixed solvents, the kinetic behaviour is well expressed by the equations which are based on the theory of Kondo and Tokura.

Empirical Relations

Here is reported evidence from viscosity data for competitive, reversible complex formation between species of Sn(IV) or Sn(II) and Sn(IV) or methanol in methanol – carbon tetrachloride solutions of SnCl4.5H2O and SnCl2.2H2O. Empirical relations between the viscosity parameter and the salt or methanol concentrations are also reported.
