Flow Hydrodediazoniation of Aromatic Heterocycles
Molecules, 2019 Continuous flow processing was applied for the rapid replacement of an aromatic amino group with a hydride. The approach was applied to a range of aromatic heterocycles, confirming the wide scope and substituent-tolerance of the processes. Flow equipment

The Reaction of 2-Aminopyridines with Ethyl Diazoacetate
CHIMIA, 1974 It has been found that ethyl diazoacetate reacted with 2- amino-pyridines to give the corresponding 2-carbethoxy- methylaminopyridines (1). In m-xylene as solvent, thermal decomposition of the diazo ester proceeded with preferential attack on m-xylene ...

Bulky-yet-flexible carbene ligands and their use in palladium cross-coupling [PDF]
, 2019 In recent years, several classes of new N-heterocyclic carbene (NHC) ligands were developed around the concept of flexible steric bulk. The steric hindrance of these ligands brings stability to the active species, while ligand flexibility still allows ...

Advanced Materials, EarlyView.Hydrogels demonstrate material properties that mimic the mechanical and chemical environments of biological tissues. Yet, they face challenges during their integration into 3D interfaces. By identifying a class of thermoplastic hydrogels, a strategy is developed to pattern hydrogels in thermally drawn fibers.

Dorsal Raphe VIP Neurons Are Critical for Survival‐Oriented Vigilance
Advanced Science, EarlyView.DRNVIP neurons in mice and primates are strategically positioned to influence the central extended amygdala via feedback loops. They regulate the excitability of PKC‐δ neurons in the ovBNST and CeA through glutamate release. Their ablation heightens activity in these regions, disrupts active‐phase sleep architecture, enhances risk assessment behaviors ...
