Summary: Soluble tetrabutylammonium ferrates were synthesized and evaluated as stand-alone catalysts in CO2 cycloaddition reactions. The catalysts showed high activity and good yields of cyclic organic carbonates without the need for additional Lewis bases as co-catalysts.

Summary: Simple ammonium ferrates serve as efficient catalysts for the coupling of carbon dioxide with aziridines to produce 5-substituted 1,3-oxazolidin-2-ones under mild reaction conditions. The reaction mechanism involves a single ferrate molecule and the closure of the 1,3-oxazolidin-2-one ring, with a barrier compatible with experimental conditions.

Summary: This article discusses the application of early-metal-based catalysts incorporating natural chiral pool motifs, such as amino acids, terpenes, and alkaloids, in hydroamination reactions, and compares them to catalysts beyond the chiral pool. It describes alkaline (Li), alkaline earth (Mg, Ca), rare earth (Y, La, Nd, Sm, Lu), group IV (Ti, Zr, Hf) metal-, and tantalum-based catalytic systems, which have significantly improved in recent years and become more practical. The emphasis is on their catalytic performance, including yields, regio- and stereoselectivity, compared to group IV and V transition metals and commonly used rare earth metal-based catalysts.

Summary: This study investigates the mechanisms of ligand rearrangement in octahedral chiral-at-metal complexes. The lowest energy cis isomer and its interconversion with other isomers are calculated. The connectivity of all enantiomeric minima and transition structures is summarized, and the influence of N-substitution on the favored pathway is evaluated.

Summary: The report explores a potential method based on a hydroboration/copper-catalyzed carboxylation reaction sequence to synthetically access fluorinated carboxylic acids. DFT calculations support the possibility of obtaining these compounds from simple fluorinated alkenes and gaseous carbon dioxide. This paves the way for the future preparation of this class of chemicals.

Summary: Dialkylaluminium amides iBu(2)Al(TMP) and iBu(2)Al(HMDS) catalyze the hydroboration of ketones to form boronic esters, but stoichiometric reactions without ketones lead unexpectedly to ring-opening of pinacolborane. X-ray crystallography reveals the formation of dimeric Al-B products, while DFT calculations support a sigma-bond metathesis mechanism involving London dispersion interactions.

Summary: An iron(II)-catalyzed polymerization of arylallenes has been reported, generating high molecular weight polymers at room temperature. The polymer structures and chain lengths of various monomers were determined using NMR, DSC, and GPC analysis. Mechanistically, it is proposed that chain growth occurs through a reactive Fe(III) species, rather than the formation of an iron(II) hydride in situ.

Summary: This study creates selectivity and activity maps by analyzing the catalyst-solvent interplay, which can be used to predict and optimize the outcome of competing reactions. The experimental results demonstrate that choosing the appropriate catalyst and solvent can simultaneously optimize catalytic activity and selectivity.

Summary: By starting from nitroarenes and using hydrosilylation conditions with a well-defined N-heterocyclic carbene iron(0) catalyst, aniline derivatives were successfully produced in moderate to high yields. Furthermore, a selective synthesis of cyclic amines such as pyrrolidines, piperidines, and azepanes was achieved from levulinic acid, 1,5- and 1,6-keto acids, respectively, with isolated yields up to 69% under visible light irradiation and thermal conditions.

Summary: This study investigates the iron-catalyzed oxidative addition of C(sp(n))-X bonds using density functional theory. The results show that the strength of the bonds increases from C(sp(3))-X to C(sp(2))-X to C(sp)-X, while the reaction barrier decreases. The analysis reveals that this decrease in barrier is due to the relief of steric repulsion between the catalyst and substrate, which is caused by the decreasing coordination number of the carbon atom. The study highlights the similarities between iron-based catalysts and palladium analogs in the oxidative addition step of cross-coupling reactions.

Summary: In the global effort to combat climate change, the design and development of new procedures for complex chemical multi-step reactions play a crucial role in the transformation of the chemical industry. Solvent effects on thermodynamics and kinetics are important considerations, with various roles including promoting intermediate formation but also compromising overall pathways. Solvent coordination is critical for the activity of reducing catalysts, impacting regioselectivity and reaction rates in complex multi-step reactions.

Summary: In this article, density-functional theory calculations are used to study the energetics of CO2 reduction to methane via the Sabatier reaction on sulfur-based transition-metal dichalcogenides (TMDs) with non-, Ni- and Cu-doping. It is found that sulfur-based TMDs with Ni/Cu doping exhibit better indicators for catalytic performance of the CO2 reduction reaction compared to non-doped and doped TMDs without active sites. Furthermore, the role of the chalcogen and dopant atoms in influencing bonding strength and type is found to have a much bigger influence on the reaction than the transition metal.

Summary: By following green chemistry principles, a zinc curcumin complex was synthesized and used as a sustainable catalyst for the synthesis of cyclic carbonate from CO2 and epoxides. The complex exhibited outstanding catalytic activity and showed potential for the synthesis of renewable carbonates.
