DESIGN AND SYNTHESIS OF PURINE BASED NEUROPROTECTORS AND NOVEL SYNTHETIC METHODS FOR THE TRIFLUOROMETHYLATION OF ALDEHYDE HYDRAZONES
… species (ROS).</p> <p>The C(sp<sup>2</sup>−H)-trifluoromethylation of hydrazones would give access to the αtrifluoromethylated hydrazones that can serve as intermediates in the synthesis of pharmaceutically interesting, fluorinated compounds. Herein, we demonstrate two different synthetic …

Carbon-trifluoromethyl bond forming reactions and palladium-catalyzed cyanation of (hetero)aryl halides
… to the development of the first system for the trifluoromethylation of aryl chlorides. Chapter 2 A method for the oxidative trifluoromethylation of (hetero)aryl boronic acids is reported. Bench top setup and visual reaction monitoring makes this process particularly well suited to medicinal and …

Fluorine-containing fullerenes and endometallofullerenes: synthesis, structure, and spectroscopic characterization
… to have superior electron-accepting properties. Trifluoromethylation of a sample of insoluble hollow higher fullerenes resulted in the structural characterization of several new dodecakis(trifluoromethyl) fullerene compounds, and this led to the first experimental observation of fullerenes …

Direct ⍺-C–H Functionalisation of Cyclic Alkylamines
… intermediates enabled the α-alkylation and α-trifluoromethylation across a range of piperidine-based systems. Furthermore, the formal C–H functionalisation sequence was successfully applied to the late-stage modification of complex bioactive molecules, underscoring the potential of this …

Part I: Design, synthesis, and studies of novel age-inhibitors and age-breakers; Part II: Novel synthetic methods for organofluorine compound
… We have also developed a novel NHC-catalyzed trifluoromethylation of aromatic N-tosyl aldimines with electron-withdrawing as well as electron-donating groups on the aryl ring. We have synthesized a series of novel purine-based triazole derivatives as potential CDK-inhibitors and characterized …

Carbon dots as sustainable photocatalysts for organic synthesis
… potential of this reaction, the net-oxidative trifluoromethylation was coupled to H<sub>2</sub>-evolution, thereby generating two products simultaneously: a trifluoromethylated aryl and feedstock for hydrogenation. Chapter 3 subsequently introduces CDs as photocatalysts for net-reductive …

Development of Novel Methods for the Installation of Trifluoromethyl/Boryl and 1,2,4-Oxadiazole Moieties
… via a stereoretentive radical trifluoromethylation with inexpensive reagents NaSO2CF3 and TBHP with copper catalysis at room temperature. Under these conditions, a wide substrate scope afforded the (E)‐diastereomer exclusively in moderate to good yield. The reaction products' …

Modifying electronic and solid-state properties of fullerenes, polycyclic aromatic hydrocarbons, and perylene diimides
… and characterized for the first time. Trifluoromethylation of azulene systematically increases the electron-withdrawing strength and affects solid-state packing motifs. The molecular structures and solid-state packing of four other families of fluorine-modified polycyclic aromatic …
