ABSTRACT: Oxygenation of a tricopper(I) cyclophanate (1) affords reactive transients competent for C−H bond activation and O atom transfer to various substrates (including toluene, dihydroanthracene, and ethylmethylsulfide) based on 1H NMR, gas chromatography/mass spectrometry (MS), and electrospray ionization (ESI)/MS data. Low product yields (
