Facile Access to N‐Substituted Pyridyl Ligands

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A modular, robust, and versatile Buchwald–Hartwig amination protocol that enables the rapid synthesis of bipyridine, phenanthroline, terpyridine, and pybox ligands bearing dialkylamine, diarylamine, and heteroaromatic N‐substituents. Pyridyl motifs equipped with N‐substituents can be powerful ligands for catalysis, yet their broader adoption is limited

Learning from B12 enzymes: biomimetic and bioinspired catalysts for eco-friendly organic synthesis

Beilstein Journal of Organic Chemistry, 2018
Cobalamins (B12) play various important roles in vivo. Most B12-dependent enzymes are divided into three main subfamilies: adenosylcobalamin-dependent isomerases, methylcobalamin-dependent methyltransferases, and dehalogenases. Mimicking these B12 enzyme

Generation of a Ground‐State Electron Donor Utilizing Stored Light Energy

Chemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.
Chemically stored light energy enables the generation of dianion reductants (∼−2.7 V) from vicinal diols derived from diaryl ketone photodimerization. These ground‐state electron donors efficiently reduce challenging substrates at room temperature, including aryl bromides, alkyl iodides, and sulfonamides.
