Self‐assembly and Lateral Cobalt Coordination of a Fivefold Symmetric Cyanostar Macrocycle on an Au(111) Surface

open access: yesChemistry – A European Journal, EarlyView.
Herein, we report the first example of the formation of a close‐packed, regular 2D monolayer of a fivefold symmetric cyanostar macrocycle on an Au(111) surface under ultra‐high vacuum and the structural modification of such self‐assembled architecture upon cobalt atom deposition.

Harnessing Toluene Solvent as a Reactant: Regioselective Benzyl Radical Addition to Multi‐π 1,5‐Enynes in a Copper‐Catalyzed Cascade to Indenes

open access: yesChemistry – A European Journal, EarlyView.
A copper‐catalyzed three‐component radical cascade of 1,5‐enynes with toluene and benzoic acids enables regioselective benzyl radical addition to multi‐Π systems, efficiently delivering polysubstituted indenes from an abundant solvent feedstock. ABSTRACT C─H activation of toluene generates a benzyl radical that undergoes C─C coupling, converting an ...

Late‐Stage Phenylation From [13C6] and [2H5]Benzene: A Versatile Tool for Stable Isotope Labeled MS Standards

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT We explored aryl thianthrenation as a tool for directly incorporating multiple isotopes into molecular scaffolds starting from full isotopically labeled benzene. Stable isotope‐labeled (SIL) molecules are indispensable tools for investigating chemical and biological mechanisms and quantifying metabolites.

It's a Gas: Bioconjugation With Vapor‐Phase Reagents

open access: yesChemistry – A European Journal, EarlyView.
Gaseous reagents are an emerging class of bioconjugation reagents that can offer alternative selectivity paradigms for the construction of precise bioconjugates. A variety of both inert and highly reactive gases have recently been developed for bioconjugation use.

Chemo‐Enzymatic Route for Covalent Cellulose Fiber Dyeing

open access: yesChemistry – A European Journal, EarlyView.
This work presents a proof of concept for a chemo‐enzymatic approach to the covalent dyeing of cotton fibers. Laccase/TEMPO oxidation introduces aldehyde groups, enabling subsequent reductive amination with amino dyes. Excellent color homogeneity and wash fastness were demonstrated using acid red 33, highlighting the robustness of the approach and its ...
