Rational Optimization of Self‐Reporting Alcohol‐Oxidizing RhIII$^{\mathrm{III}}$ Complexes

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A series of four different [(NN)Rh(Cp*)X]n+$^{\mathrm{n+}}$ complexes (NN = chelating α$\alpha$‐diimine ligand, Cp* = pentamethylcyclopentadienyl, X = Cl, solvent) are reported which all do possess a colorimetric self‐reporting property upon alcohol oxidation formation of the Rh(I) state. Analysis of alcohol oxidation rates

On the Planarity of Heterocyclic Bay‐Substituted Perylenediimides: Insight into the Fluorescent Photoinduced Electron Transfer Sensing Framework

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Near‐infrared fluorescent pH indicators based on perylenediimide were constructed in a modular receptor–spacer–fluorophore–spacer–receptor format with heterocyclic amino moieties at the bay positions. Counterintuitively, the dibrominated intermediate with two heavy atoms is more emissive than the heterocyclic compounds.

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 ...

Hofmann Degradation of Asparagine and Glutamine as an Efficient Approach for the Synthesis of Derivatized Lysine Homologs

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A practical and scalable route to C1 and C2 lysine homologs has been developed using Hofmann degradation of N‐protected L‐asparagine and L‐glutamine as the key step. These short‐tether scaffolds enable efficient synthesis of diverse Fmoc‐protected noncanonical amino acids (ncAAs) bearing donor, acceptor, redox‐active, and fluorescent residues.

Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a
