Conditions: molar ratio of [catalyst:H₂O₂:substrate]= [1:1000:2500] in 1 mL of CH₃CN (1 equiv = 1 μmol).

Conditions: molar ratio of [catalyst:HCl:H₂O₂:substrate]= [1:100:1000:2500] in 1 mL of CH₃CN (1 equiv = 1 μmol).

Yields based on the starting substrate and products formed. The mass balance is 98–100%. The reaction time was 6 h.

TON: total turnover number, moles of products formed per mole of catalyst.

TOF: turnover frequency which is calculated by the expression [products]/[catalyst] × time (h^–1).
