The remaining 25% of mix-1 is represented by mesomeric R,S-1 which nominally plays a spectator role in both C-H and C[double bond, length as m-dash]C bond oxidation reactions. Overall, this mixture of iron complexes displays the same catalytic profile as its enantiopure components that ...
Copper-Catalyzed C-C(O)C Bond Cleavage of Monoalkylated β-Diketone:Synthesis of α,β-Unsaturated Ketones A new and simple route for the synthesis of α,β-unsaturated ketones via cleavage of the C-C(O)C single bond of monoalkylated β-diketone has been describ... Tony Wheellyam Pouam...
Thus, the change in BDE with an increase in the length of pre-strained weak C–C bonds (>1.7 Å) should be smaller than the energy required to lengthen a normal C–C bond (1.54 Å) to the same degree. We very recently found that the expanded bond in some tetraarylpyracenes 9 ...
To gain further insights into this enzyme, we determined the structure of CalA3 by cryo-EM analysis and reconstituted the in vitro amide bond formation reaction. We purified full-length His-tagged CalA3 using a nickel column, then a heparin column, and finally a size-exclusion column (Suppleme...
Palladium forms 5–6-membered metallacyle, which reacts with norbornene to provide an intermediate, followed by the activation of meta-C–H bond and subsequently the aryl coupling partner forms new C–C bond then β-carbon elimination of norbornene and protodemetallation of the aryl–palladium ...

The inhibited internal rotation about the C-N partially double bond in N-acyl-1,2,3,4-tetrahydroquinolines was investigated by NMR spectroscopy. It is demonstrated that these compounds exist in the form of Z and E conformers, and their ratios are determined under the conditions of stereochemica...
