spectrometry and UV/Vis data. The catalytic activity of 1–4 as homogeneous catalysts in the aerobic oxidation of 4‐methoxybenzyl alcohol and 1,2‐diphenyl‐2‐methoxyethanol was explored. 1 and 2 showed moderately superior activity compared with 3 and 4, which might be due to increased stability of these complexes. 1–4 showed limited reactivity in H2O2‐mediated oxidation of diphenyl ether and benzyl phenyl
