Copper Complexes with Arylated Triethylenetetramine Ligands: Reactivity Toward Dioxygen and Peroxides

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Here, we describe new Cu(I)/Cu(II) complexes based on arylated tren ligands and investigate their reactivity toward O2 and peroxides. Low‐temperature–stopped flow studies revealed the formation of transient copper–oxygen species, including superoxido, hydroperoxido, and alkylperoxido intermediates.

Emerging Trends in Organic Photoreactions Utilizing Disulfides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Disulfides are versatile, nontoxic alternatives to metal photocatalysts. This review explores their role as photoactivated thiyl‐radical precursors and bifunctional catalysts (HAT/electron shuttling) in diverse transformations. Strategies for electronic tuning and development into recyclable heterogeneous materials are highlighted for sustainable ...

Preparation of α‐Mono‐Fluoromethyl Silanes via Nucleophilic Displacement on Chlorosilanes With LiCH2F

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The SiCl bond acts as a versatile platform for undergoing a formal nucleophilic substitution promoted by LiCH2F en route to extremely rare α‐monofluoromethyl‐silanes. Though surprising – when compared with well‐established poly‐fluoromethyl silanes (e.g., Ruppert‐Prakash reagent, TMSCF3) – α‐mono‐fluoromethyl silanes are underrepresented motifs in ...
