Strategies that enable intermolecular site-selective C–H bond functionalisation of organic molecules provide one of the cornerstones of modern chemical synthesis. In chloroalkane synthesis, such methods for intermolecular site-selective aliphatic C–H b
Importantly, its FT-IR spectrum also showed peaks associated with covalent C–OH bonds that were not observed in the FT-IR spectrum of fluorographene, namely a C–O vibra- tion peak at 1,058 cm–1 and a broad O–H vibration peak at NATURE COMMUNICATIONS | 8:14525 | DOI: 10.1038/n...
All glassware was oven dried at 100 ºC before use. All solvents were distilled from appropriate drying agents prior to use. All reagents were used as received from commercial suppliers unless otherwise stated. Neat infra-red spectra were recorded using a Perkin-Elmer Spectrum 100 FT-IR ...

These fully genetically encoded enzymes are produced and function in bacteria, where they can be optimized by directed evolution for a broad spectrum of enantioselective C(sp3)–H amination reactions. These catalysts can aminate a variety of benzylic, allylic and aliphatic C–H bonds in excellent ...
The supernatant was collected and stored at 4 °C until further use. The absorption spectrum (400–1000 nm) was recorded for every suspension with a spectrometer (Cary 5000). The concentration of the PL-PEG-coated SWCNT was estimated to be 0.36 µg mL−1 based on the ...
Such conditions can shift the absorption spectrum into the visible region, resulting in a noticeable color of the complex. Table 2. Selected IR data of each ligand and its complexes (cm−1). 2.2. Photocatalytic Property Previous studies have demonstrated that uranyl(VI) can serve as an ...
Scheme 9. Cu-catalyzed visible-light-driven stereoselective α-C(sp3)–H glycosylation of glycine derivatives. The photoactive copper complex possesses the inherent advantage over the Ru or Ir complex regarding availability and cost [76,77,78,79]. Therefore, it has become an effective photocatalys...
