Figure 8.
Plot of kobsd vs Et3N concentration in toluene for the enolization of 1 (0.0050 M) with LiHMDS (0.10 M) at 0 °C measured with IR spectroscopy (1671 cm–1). The curve depicts an unweighted least-squares fit to y = axn [a = 0.53 ± 0.03, n = 1.00 ± 0.03]. Analogous linearity and reaction order are replicated by the more complex function described in the text.
