note

A slow side reaction between diphenylacetylene and the reactant and product imines was catalyzed by 6b. This resulted in the complete consumption of diphenylacetylene over a period of 4 days, leaving diazametallacycles 3 as the predominant Zr-containing species.

note
-
eq value of 7.4 for the 6a/3a interconversion at 70°C is incorrect because of the misinterpretation of spectroscopic data. The equilibrium value was remeasured at 75°C at three different concentrations of 3a, and the spectral data were compared with those for authentic samples of 6a and 3a.

note
-
Complex 10a was not chosen as the catalyst precursor for the kinetic measurements because its imine adducts analogous to 3 exist as pairs of diastereomers. It was thought that this would further complicate the already complex system.

eq measurements in eq 3 predict that, at equilibrium, less than 10% of 6b should be converted to diazametallacyclobutanes 3.

note

The parameters chosen initially for the experimental data fitting were based on rate constants experimentally determined from previous kinetic studies of the stoichiometric reactions. These parameters were then adjusted to obtain the best fit for the eight experimental runs. Final optimization of the model was accomplished by application of a nonlinear least-squares fitting routine. Simulations were allowed to converge, then restarted at the convergence point. This process was repeated until no further variations were seen in the rate constants. Rate constants obtained after convergence were still in agreement with independently measured equilibrium and rate constants.
