Advances in the Different Synthetic Routes of Fluorinated Hydrazines
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.

Facile Access to N‐Substituted Pyridyl Ligands
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

A reactivity programmed cascade between carbyne equivalents and allylic benzoates was developed that sequentially orchestrates all three reactivity modes of carbyne equivalents, enabling the rapid installation of three σ‐bonds at a single carbon center and providing efficient, scalable access to structurally diverse spirocyclic ethers. ABSTRACT Carbyne

Direct Mechanoorganocatalysis via Surface Functionalization of Milling Reactors With Amine Functions
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.

Regioselective Tele‐Substitution of Aroyl Chlorides via Activation by an Al/P Frustrated Lewis Pair
A tele‐substitution of aroyl chlorides with silyl ketene acetals is enabled by an ortho‐phenylene‐linked Al/P frustrated Lewis pair. Intramolecular aluminum activation polarizes the aroylphosphonium intermediate, promoting regioselective dearomative nucleophilic addition to the aromatic ring.

Photochemically excited levoglucosenone (LGO) efficiently undergoes Norrish type I reactions yielding particularly functionalized alkenes. In the presence of tertiary amines, this reaction is quenched by an intermolecular electron transfer. This process leads to addition products with high stereoselectivity.
