Clean 1H NMR Spectra of Products Directly from Batch and Flow Reaction Mixtures

ChemistryEurope, EarlyView.
Time‐resolved diffusion nuclear magnetic resonance (NMR) is a valuable tool in reaction monitoring. and multiway analysis of such data can provide access to the individual spectraof reaction components. Herein, batch and flow reactions are analysed using flow NMR to obtain the spectrum of newly‐formed products.

Synthesis and Aggregation of Amphiphilic Porphyrin‐Perylenebisimide Dyads

Chemistry – A European Journal, Accepted Article.
We report the straightforward synthesis of a family of amphiphilic zinc‐porphyrin‐perylenebisimide dyads containing sterically demanding substituents at the porphyrin meso‐position, as well as at the PBI bay position. The hydrophilic head group consists of oligo‐carboxylic acid G2‐Newkome dendrons attached to the porphyrin, whereas lipophilic pentyl ...

Topographic thresholds for gully head formation in badlands

Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3558-3587, December 2022., 2022
Gully topographic threshold model was extended to badlands, on the basis of data collected in the Mediterranean environment in Italy and Spain, characterized by diversified climatic, lithological, geological and anthropogenic settings. Criteria for the attribution of curve number values has been more objectively defined in order to reduce arbitrariness

Oxidation‐Deformylation Cascade Catalyzed By a Mononuclear Copper Complex

Chemistry – A European Journal, EarlyView.
A bioinspired copper complex is able to catalyze two successive oxidative steps of alcohol conversion in the presence of hydrogen peroxide under mild conditions: (i) alcohol oxidation to aldehyde and (ii) aldehyde deformylation. Isotopic effects on the reaction rates indicate that hydrogen atom abstraction is rate limiting for both steps.

Endohedral Coordination of Bulky Substrates in Metalloenzyme‐like Organometallic Nanotubes

Chemistry – A European Journal, Accepted Article.
Artificial receptors inspired by metalloenzymes share three key properties: a structurally flexible cavity, substrate binding via metal–ligand coordination, and metal‐based redox activity. Herein, we report an organometallic nanotube with such features based on our supramolecular pillarplex platform, with eight CuI centers integrated in its cavitand ...
