Plot of initial rate versus [ArLi] for the ortholithiation of ArH (0.0050 M) by 0.10 M LDA in 12.2 M THF monitored with IR spectroscopy at −78 °C. The curve depicts an unweighted least-squares fit to eq 11. Solid curve: a = 2 ± 4, b = (3 ± 8) × 106, c = 2.94 × 10–6, n = 3.0 ± 0.5. Dotted curve: n is set at 2; a = (9 ± 2) × 10–2), b = (1.7 ± 0.3) × 104, c = 2.94 × 10–6.
