Summary: Using DFT method, the reaction mechanism of ethanol formation over the Cu-4/MoS2 catalyst was explored, and it was found that CO is first hydrogenated to formyl, which is further dissociated to form CH2 leading to the formation of ethanol. The Cu-4 cluster provides undissociated CO and CHO, while the interface between Cu-4 and MoS2 promotes the process of ethanol synthesis.

Summary: (NDI)Ni-2 catalysts promote cyclopropanation reactions of 1,3-dienes by coupling with (Me3Si)CHN2. Mechanistic studies and DFT models suggest an alternative reaction mechanism involving Ni-2 mediated coupling and N-2 extrusion for generating cyclopropane products, explaining the experimental observations.

Summary: By systematically investigating the oxygen reduction reaction process on dual-metal-nitrogen-carbon catalysts through first-principle calculations, it is found that the high activity of dual-metal sites can be attributed to facilitating O-O bond cleavage and mitigating *OH removal issue. The introduction of a descriptor called antibonding center simplifies the evaluation of kinetics.

Summary: Salt-stabilized organozinc pivalates with OPiv-coordination exhibit significant counterion-effect, enabling an efficient cobalt-catalyzed 1,4-carbosulfonylation of 1,3-enynes with sulfonyl chlorides under mild conditions. Both aryl and alkyl zinc pivalates show higher reactivity compared to traditional halide-supported organozinc reagents, providing a convenient access to highly functionalized a-allenyl sulfones through cascade C-C/C-S bond formation. Additionally, late-stage modifications of drug-like compounds and facile transformations of the resulting allenes demonstrate the synthetic utility of this protocol.

Summary: Herein, a 1,3-rearrangement reaction of allylic alcohols catalyzed by an Ir(III) dihydride complex is described. The reaction selectively provides the corresponding less accessible allylic alcohols from E/Z mixtures of the substrates. Furthermore, a tandem alkene isomerization followed by 1,3-rearrangement of homoallylic alcohols was also achieved. The rearrangement reaction could be used to synthesize the natural product Navenone B. Mechanistic investigation revealed the involvement of a pi-allyl-Ir(V) intermediate and the modulation of iridium center valence by the dihydride in the iridium catalyst.
