Fused Nitrogen Bridgehead N,O‐Acetals as Versatile Scaffolds: Synthetic Strategies, Mechanism and Applications

Chemistry – A European Journal, EarlyView.
Fused nitrogen‐bridgehead N,O‐acetals receive specific emphasis as pivotal scaffolds due to their significant role in the bioactivity of medicinally relevant molecules. Significant approaches have been reported on their role as key synthetic building blocks/motifs in the construction of complex organic molecules and their utility as chiral auxiliaries ...

3,4,5‐Trifluorophenyldiazonium – a unique radical source for the visible light induced, catalyst‐free arylation of tyrosine residues in peptides

Chemistry – A European Journal, Accepted Article.
The direct radical arylation of tyrosine residues in peptides has been achieved under highly attractive conditions, requiring only the peptide substrate, a 3,4,5‐trifluorophenyldiazonium salt and irradiation with visible light. Being well‐balanced in its reactivity to form strong charge transfer complexes with the phenolic side chain, which are ...

Ultrasmall Gold Nanoparticles (2 nm) Decorated with a High Density of Photochemically Switchable Ligands

Chemistry – A European Journal, EarlyView.
Photoswitchable azo ligands can be conjugated to the surface of ultrasmall gold nanoparticles with a high density (about 50 ligands on each nanoparticle). Their photoswitching is not constrained by the binding to the gold surface and can be used to induce a nematic‐to‐isotropic phase transition in a liquid crystal.

Reactions of 1,4‐Diborinine Derivatives with CO2

ChemPhysChem, EarlyView.
The reaction of CO2 with seven molecules featuring a 1,4‐diborinine central ring is studied by means of density functional theory calculations. The selected systems present five‐ and six‐membered aza rings surrounding 1,4‐diborinine. The computed reactivity trends and origin of regioselectivity are quantitatively analyzed with the activation strain ...

Diazonium Salts in Visible Light Photocatalysis – a Focused Overview of their Application in Continuous Flow Synthesis

ChemPhotoChem, EarlyView.
The combination of continuous flow technology and visible light photocatalysis has been used to improve the safety and productivity of reactions with diazonium salts as reactive intermediates. This approach has proven to be a reliable method for various organic synthesis routes with diazonium salts under mild and well‐defined conditions.
