A catalytic cycle involving the coordination of nitrile trans to the pincer backbone after an initial hydride rearrangement at the ruthenium center, and the subsequent first transfer of the hydride ligand to the carbon center of the nitrile ligand is suggested as a possible reaction mechanism. ...
1.19.1.3.7 Formation of carbanions by scission of CN bonds The mechanism of the Wolff–Kishner reduction of aldehydes and ketones involves transient carbanion formation as a result of the cleavage of a CN bond leading to the evolution of a molecule of nitrogen. This and related reactions have...
The electrochemical reduction mechanism of isophthalonitrile (1,3-benzenedicarbonitrile) has been investigated by cyclic voltammetry and polarography. In anhydrous DMF, the anion radical formed by quasi-reversible one-electron transfer undergoes dimerisation through radical—radical coupling. Comparison of the...
Proposed relay catalysis mechanism (color online). 3 Conclusions In summary, we have demonstrated that the IrCl(CO)(PPh3)2/B(C6F5)3/TMDS combination constituted a very efficient, mild, and chemoselective protocol for the reduction of tertiary amides to amines. The method can be used for the...
The impact of this binding is very large in terms of reaction rate and at the same time gives rise to unique mechanistic phenomena, which include unusual kinetic rate orders, catalysis by quantum dots, and remote functionalization. Even reduction of nitriles was found to be affected by this ...

Next, we sought to explore the scope and limitations of this photoenzymatic reaction. Pleasingly, a wide variety of nitroarenes are well accepted by BaNTR1 (Fig.2, Suppl. Fig.2, and Suppl. Fig.3). Nitroarenes possessing electron-withdrawing groups such as halogens, nitrile and trifluorometh...
3.6. Mechanism and kinetic discussion Selective reduction of 4-NiP follows the adsorption of BH4¯ and 4-NiP on to the catalyst surface. Reduction occurs by the transfer of electrons from BH4¯ to 4-NiP through the catalyst surface. The catalyst surface activity is playing a pivotal role ...
