Figure 1

UV–vis spectra change for formation of (a) 2 and (b) 2′. Complex 2 or 2′ (orange) from a reaction of 1 or 1′ (black, 0.4 mM) with O2 in THF at −80 °C. Inset: rR spectra of 2 or 2′ (7.5 mM) in CH2Cl2 (λex 457 nm, 10 mW, 77 K; red line: 2-16O or 2′-16O, blue line: 2-18O or 2′-18O, black line: difference spectrum 2-16O – 2-18O or 2′-16O – 2′-18O). Asterisks denote solvent peaks.
