The aim is to understand how copper nuclearity influences oxidation reactions in sulfur-donor environments.
Utilized tert-butyl substituted dithioether-dithiolate ligands to modify copper(II) assembly.
Conducted spectroscopic, electrochemical, and DFT studies to assess complex behavior.
Examined aerobic oxidation of substrates 3,5-di-tert-butylcatechol and o-aminophenol.
Binuclear [CuS 4 ] 2 shows stronger substrate binding (K M 3.4 mM) compared to mononuclear [CutBuS 4 ] (K M 5.0 mM).
Maximum turnover frequencies are similar for both complexes, approx. 1700–1750 h − 1.
Oxidation activity is higher for binuclear [CuS 4 ] 2 versus mononuclear [CutBuS 4 ] (2772 vs. 684 h − 1).
