Tuning Reactivity in Cu/TEMPO Catalyzed Alcohol Oxidation Reactions

open access: yesChemistry – An Asian Journal, EarlyView.
Novel copper(I) complexes bearing a secondary amine moiety (CuL3) or an additional non‐innocent functionality with intact imine group (Cu2L42) were synthesized and tested towards oxidation reactions. Several intermediates, such as Cu(III)2(bis‐μ‐oxo) and Cu(II)2(bis‐μ‐hydroxo), species were trapped and spectroscopically characterized.

Mechanistic evaluations of photocatalytic access to N‐centered radicals and nitrenoids

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Recently, the photocatalytic formation of reactive N‐centered radicals or nitrenes from prefunctionalized amine precursors via single‐electron transfer (SET) or triplet–triplet energy transfer (TTEnT) has been significantly developed. However, the detailed electron flow during N–X bond cleavage leading to these intermediates remains unclear. Herein, we
