Plot of initial rate vs lithium 2,2,6,6-tetramethylpiperidide (LiTMP) concentration for the metalation of 1 (0.010 M) in 6.0 M THF/hexane at –78 °C measured with IR spectroscopy (1323 cm–1). The curve depicts an unweighted least-squares fit to eq 5 that accounts for the shifting dimer–monomer mixtures described by eq 4. A simple fit to y = axn affords a = 33.07 ± 2.19, n = 0.97 ± 0.04.
