Oxidation of methane by an N-bridged high-valent diiron-oxo species: electronic structure implications on the reactivity. High-valent iron-oxo species are key intermediates in C-H bond activation of several substrates including alkanes. The biomimic heme and non-heme mononucle... Mursaleem,Ansari...
However, the reaction of silacyclobutanes with alkynes still suffers from some limitations: (1) internal alkynes remain challenging substrates; (2) expensive Pd- or Rh-based catalysts have been employed in all existing systems; (3) controlling chemodivergence has not yet been realized. Herein we...
Nickel-catalyzed C–H bond functionalization reactions provide an impressive alternative to those with noble metal catalysts due to their unique reactivity and low cost. However, the regioselective C(sp2)–H borylation reaction of arenes accomplished by

reactivity (for reviews, see Burrows and Rokita32,33). Moreover, nickel complexes are able to catalyze site-specific oxidative damage to DNA.109Such complexes can also be used to probe RNA structure.110Analogous cobalt(II) complexes show similar reactivity with unpaired guanine residues in both ...
A significant amount of functionalized amine R–NHAd is observed in the reaction of 1 with indane along with the dinickel imide {[Me3NN]Ni}2(μ-NAd) (5). Kinetic and DFT analyses point to rate-limiting HAA from R–H by 1 to give R, which may add to either imide 1 or amide 2,...
Similarly, maxima in the production rates coincided with minima in the ESEM average image intensities. Fig. 3: Self-sustained oscillations of DRM occurred on a Ni catalyst. a, Time series of the temperature, reactor pressure, average image intensities and mass spectrometry signals of reactants ...
