Study and characterization of modified silicon surfaces with organic molecules [PDF]

, 2016
Nanostructured thin films and subsequent biofunctionalization of silicon substrates are essential for the development of biosensors devices. The formation of organic monolayers on silicon substrates via Si-C bound allows specific interactions with ...

Recent Synthetic Advances in C–H/N–H Functionalization of 1H‐Pyrazoles: Diverse Strategies Across Variously Substituted Scaffolds

The Chemical Record, Volume 25, Issue 12, December 2025.
Systematic overview of pyrazole functionalization reactions from C‐5 to N−H. It covers different strategies, from traditional cross‐coupling of prefunctionalized pyrazoles to more efficient direct functionalizations. This review briefly and systematically overviews C–H and N–H functionalization reactions of pyrazoles, aimed at creating new CC and C ...

Benzo‐fused Nitrogen Heterocycles by Asymmetric Ring Expansion and Stereochemically Retentive Re‐contraction of Cyclic Ureas

Angewandte Chemie, Volume 136, Issue 12, March 18, 2024.
Asymmetric deprotonation of N‐benzyl urea derivatives of nitrogen heterocycles leads to enantioselective insertion of the benzylic substituent into an aromatic C−N bond. Treatment of the ring‐expanded products induces a stereospecific ring‐contraction that results in an overall asymmetric enantioselective one‐carbon enlargement of the heterocycle ...

Multistep Reactions Initiated by Amine‐Based Organometallic Methods

European Journal of Organic Chemistry, Volume 28, Issue 40, October 29, 2025.
The advent of C–H activation and other organometallic methodologies making use of transient directing groups or free amines themselves for the elaboration of amine substrates provides unique access to cascade‐type reactions that can generate significant molecular complexity in one pot. The pursuit of atom‐ and step‐economical pathways to access complex

Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates

ChemCatChem, Volume 17, Issue 15, August 7, 2025.
The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...
