Advances in the Different Synthetic Routes of Fluorinated Hydrazines

The Chemical Record, EarlyView.
This review highlights the various routes to the preparation of fluorinated hydrazines, thereby promoting the exploration of innovative methods for the synthesis of new N‐fluorinated hydrazines. Their synthesis mainly involves synthetic routes such as organometallic, organocatalytic, and photocatalytic.

Experimental and Theoretical Evidence for Nitrogen-Fluorine Halogen Bonding in Silver-Initiated Radical Fluorinations [PDF]

, 2019
We report experimental and computational evidence for nitrogen–fluorine halogen bonding in Ag­(I)-initiated radical C–H fluorinations. Simple pyridines form [N–F–N]+ halogen bonds with Selectfluor to facilitate single-electron reduction by catalytic Ag ...

Catalytic Enantioselective Synthesis of Conformationally Stable C(sp2)−C(sp3) Naphthocoumarin Atropisomers

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
The enantioselective synthesis of naphthocoumarin adducts via a tandem organocatalytic 1,4‐addition/decarboxylation delivers excellent control over a newly forged stereocenter and yields configurationally stable synclinal atropisomers. The process features broad substrate scope and scalability, and its structural and mechanistic foundations are ...

Recent advances in organocatalytic atroposelective reactions

Beilstein Journal of Organic Chemistry
Axial chirality is present in a variety of naturally occurring compounds, and is becoming increasingly relevant also in medicine. Many axially chiral compounds are important as catalysts in asymmetric catalysis or have chiroptical properties. This review

Desymmetrization of Pseudo‐para Diformyl[2.2]Paracyclophane via Brønsted Acid‐Catalyzed Reductive Amination

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A highly stereoselective desymmetrization of pseudo‐para diformyl[2.2]paracyclophanes is developed via chiral Brønsted acid‐catalyzed reductive amination. This protocol provides efficient access to enantiopure planar chiral paracyclophanes with broad substrate scope, excellent enantioselectivity, and versatile postsynthetic functionalization. Access to

NHC in Imidazolium Acetate Ionic Liquids: Actual or Potential Presence? [PDF]

, 2018
Ionic liquids (ILs) are considered in the majority of cases green solvents, due to their virtually null vapor pressure and to the easiness in recycling them.

Direct Mechanoorganocatalysis via Surface Functionalization of Milling Reactors With Amine Functions

ChemistryEurope, Volume 4, Issue 5, May 2026.
Surface functionalization of milling jars in epoxy resin furnished reactive milling jars, able to perform direct mechanoorganocatalysis with high efficiency, recyclability, and simplified purification. This proof of concept was applied successfully to base‐catalyzed Knoevenagel condensation and multicomponent reactions.
