Bond activation and catalysis are central to the development of a sustainable energy system. Frustrated Lewis Pairs have conceptually revolutionized inert chemical bonds. Far less developed hybrid systems containing at least one transition metal as part electron-donating/accepting composition. These cooperative architectures present advantages over traditional systems. For instance, they incorporate, concept FLPs, movement electron pairs typically encountered in elementary steps organometallic catalysis. This Perspective presents arguably most relevant recent progress vivid field research that aspires implement designs polarized Moreover, it provides tools for future developments shows molecular control bond-making -breaking processes can be achieved.

Manganese-Catalyzed Dehydrogenative Synthesis of Urea Derivatives and Polyureas

ACS Catalysis, Journal Year: 2022, Volume and Issue: 12(12), P. 6923 - 6933

Published: May 27, 2022

Urea derivatives have significant applications in the synthesis of resin precursors, dyes, agrochemicals, and pharmaceutical drugs. Furthermore, polyureas are useful plastics with coating, adhesive, biomedical industries. However, conventional methods for urea involve toxic reagents such as (di)isocyanates, phosgene, CO, azides. We present here (poly)ureas using much less reagents─(di)amines methanol─via a catalytic dehydrogenative coupling process. The reaction is catalyzed by pincer complex an earth-abundant metal, manganese, liberates H2 gas, valuable itself, only byproduct, making overall process highly atom-economic. A broad variety symmetrical unsymmetrical been synthesized moderate to quantitative yields this protocol. Mechanistic insights also provided experiments DFT computation, suggesting that proceeds via isocyanate intermediate.

Sustainable catalysis with fluxional acridine-based PNP pincer complexes

Chemical Communications, Journal Year: 2022, Volume and Issue: 58(23), P. 3731 - 3746

Published: Jan. 1, 2022

Because of the widespread use fossil fuels and resulting global warming, development sustainable catalytic transformations is now more important than ever to obtain our desired building materials with least carbon footprint waste production. Many (de)hydrogenation reactions, including CO2 reduction, H2 carrier systems, others, have been reported using molecular pincer complexes. A specific subset complexes containing a central acridine donor flanking CH2PR2 ligands, known as acridine-based PNP complexes, exhibit special reactivities that are not imitable by other such pyridine-based or (R2PCH2CH2)2NH type ligands. The goal this article highlight unique then investigate how these allow catalyse many reactions traditional cannot catalyse. To end, we will initially go over synthesis structural features labile coordination N observed fac-mer fluxionality. Following that, distinct reactivity patterns their acids water be discussed. Finally, discuss reaction systems developed thus far, notable selective primary alcohols amines ammonia, N-heteroaromatic from oxidation liberation, conclude future possible directions.
