Abstract:
A relay photoredox catalysis strategy concomitant with [1,5] hydrogen atom transfer has been applied in the construction of a biologically important indolo[2,1-a]isoquinoline framework via a cascade reaction. This reaction enables double C(sp<sup>3</sup>)–H bond functionalization and formation of two carbon–carbon double bonds.

Abstract:
Designing highly selective and efficient double-atom electrocatalysts (DACs) is essential for achieving a superior nitrogen-reduction reaction (NRR) performance. Herein, we explored the defective boron nitride–supported cage-like double-atom catalysts to rummage the qualified NRR catalysts. Based on a systematic evaluation of the stability, N2 adsorption, NRR selectivity and activity of 10 DACs of TM1-TM2@VB-BN, we predicted Ru-Ti@VB-BN to be the NRR candidate with a limiting potential of −0.40 V. Compared to the corresponding single-atom catalysts, the introduction of Ti/Mo modulates the d-ba

Cytochromes P450 catalyse the insertion of one O 2 -derived oxygen atom in unactivated C–H bonds, and as such, are potent oxidants. A significant amount is known about the P450 catalytic cycle owing partly to the single heme group at the active site that provides spectroscopic handles in tracking various intermediates. A sophisticated array of electron paramagnetic, electron double nuclear resonance, and more traditional absorption spectroscopies have been able to identify key intermediates, while crystallography has defined the structure of the substrate-free, -bound, and oxy-complexes.

Abstract:
Configuration retaining glycosidases catalyse the hydrolysis of glycosidic bonds via a double displacement mechanism, typically involving two key active site carboxyl groups (Glu or Asp). One of the enzymic carboxyl groups functions as a general acid–base catalyst, the other acts as a nucleophile. Alternatively, configuration-retaining hexosaminidases from the sequence-related glycosidase families 18, 20, and 56 lack a suitably positioned enzymic nucleophile; instead, they use the carbonyl oxygen atom of the neighbouring C2-acetamido group of the substrate.

Allylzinc reagents were used to access highly functionalized tertiary carbinamine derivatives in high yields from cyanoesters and cyanocarbonates. While the monoaddition of organometallics on nitriles is generally observed, in this work the nucleophilic allylation occurs twice, due to an intermediate transfer of the carbonyl moiety onto the nitrogen atom. The chemoselectivity of the reaction allows the presence of various functionalities and in the case of carbonate derivatives, the nature of the final product was modulated by kinetic control, giving selectively hydroxyamides or cyclic carbama

Abstract:
Abstract Asymmetric hydrogenation has been studied intensively for a relatively long time. In its usual form the reaction involves the addition of hydrogen to a double bond in the presence of a transition metal catalyst and a chiral, notacemic ligand. As with many enantioselective reactions which involve catalysis, a substrate, ligand, metal atom, and stoichiometric reagent are all involved in the transition state of the rate determining step. A typical catalytic cycle for asymmetric hydrogenation is shown schematically in Fig. 7.1.

Abstract:
The production of ammonia is facilitated by the nitrogen reduction reaction (NRR), where the inert di-nitrogen molecule is converted to ammonia. Along with being a major carrier of hydrogen, ammonia holds authority in the fertilizer realm. Therefore, it is inevitable to develop a viable and eco-friendly method of production that is cost-effective and resource-efficient. The primary challenge of nitrogen reduction is the cleavage of the particularly stable nitrogen bond. The most popular Haber-Bosch process for ammonia production, although efficient, is highly energy-intensive, and the need for

Abstract:
This chapter addresses the reduction of carbon–carbon double and triple bonds. In particular, it examines ways of reducing multiple (π) bonds between carbon atoms by the addition of hydrogen (a process known as hydrogenation). The chapter begins by looking at the reduction of alkenes. Reaction of an alkene with hydrogen gas and one of the transition metal catalysts results in the reduction of the π-bond and formation of an alkene. The mechanism by which heterogeneous hydrogenation proceeds is complex and difficult to study as the reaction takes place on the surface of the metal, and the nature

Abstract:
Abstract Simple addition of a carbene or carbenoid to a C-N double bond would be expected to result in the formation of an azomethine ylide. This is consistent with electrophilic attack of the carbene at the nitrogen atom lone pair. Formation of ylides in this manner was reviewed by Padwa and Hornbuckle in 1991. The reaction of carbenes with simple imines (Schiff bases) to form azomethine ylides, which then undergo 1,3-dipolar cycloaddition with a second molecule of imine, was first reported in 1972. Bartnik and Mloston subsequently extended this method by using various dipolarophiles. Catalyt
