Here, by photocatalytic, reversible C–H sampling, we report a functional-group translocation reaction of cyano (CN) groups in common nitriles, allowing for the direct positional exchange between a CN group and an unactivated C−H bond. The reaction shows high fidelity for 1,4-CN ...

The direct cleavage of C(CO)−C single bonds, delivering otherwise inaccessible compounds, is a significant challenge. Although the transition metal-catalyzed insertion of functional groups into C(CO)−C bonds has been studied, strained ketone substrates or chelating assistance were commonly required...

Methyl α- and β-pyranosides of d-glucose and d-galactose 1−4 were prepared containing single sites of 13C-enrichment at C4, C5, and C6 (12 compounds), and 1H and 13C{1H} NMR spectra were obtained to determine a complete set of J-couplings (1J, 2J, and 3J) involving the lab...

To date, the construction of C-X bonds (X = O, N, Cl, Br, etc.) starting from direct activation of inert C–H bonds has been investigated intensively [[13], [14], [15]]. Traditionally, the above C–H bond transformation mainly rely on transition metal catalysts such as ...

Activation parameters for an apparent single-step metal insertion into a C-C bond were obtained. A combination of C-H and C-C activation in conjunction with oxidative addition of other bonds has led to unique methylene transfer chemistry. 展开 ...
