Ecology and evolution of pyrazines in insects

Biological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Synthesis and Characterization of π‐Extended Azulenes via Nucleophilic Substitution and Intramolecular Cyclization of 5‐Alkynyl‐6‐Fluoroazulenes

ChemistryEurope, EarlyView.
A modular synthetic approach enables the preparation of azulene‐fused heterocycles via nucleophilic aromatic substitution followed by intramolecular cyclization of alkynyl fluoroazulenes. The method allows the incorporation of various heteroatoms (N, O, S, Se, and Te), leading to structurally diverse heteroannulated azulenes.

Hydrogen Bonding is Key Factor in Reversible NH3 Uptake Causing Vapochromic and Magnetochemical Switching in Ni(II) Paddlewheel Complexes

ChemistryEurope, EarlyView.
Nickel complexes showing reversible vapochromic and spin crossover behaviors upon coordination and release of NH3 were synthesized. They bear bidentate pyridazine ligands, which allows for formation of hydrogen bonds between NH3 and the ligand in the second coordination sphere.
