Scheme 2c May 2026

In organic chemistry, is often used in reviews of nickel-catalyzed reactions , particularly those involving the formation of complex bonds.

In bioinorganic chemistry, represents a specific geometric interaction within the FeMo-cofactor of nitrogenase . Scheme 2C

: It details the characteristic ~3.7 Å Fe-Fe interactions across the cluster core. In organic chemistry, is often used in reviews

: It typically depicts a catalytic cycle where a nickel(I) species acts as the active catalyst for processes like asymmetric alkyl–alkyl bond formation . : It typically depicts a catalytic cycle where

In the context of battery technology, describes an "active interaction model" for coating nanoparticles with kitchen oils.

: While historically significant, newer research often favors alternative pathways, such as direct hydride transfer (Scheme 2D), because certain experimental observations—like the lack of a detectable covalent intermediate in all cases—make the nucleophilic path harder to verify. 2.
