An iron-catalysed, hydride-mediated reductive cross-coupling reaction has been developed for the preparation of alkanes. Using a bench-stable iron(II) pre-catalyst, reductive cross-coupling of vinyl iodides, bromides and chlorides with aryl- and alkyl Grignard reagents successfully gave the products of formal sp(3)-sp(3) cross-coupling reactions.

The highly chemo-, regio-, and stereoselective synthesis of alkyl- and vinyl boronic esters with good functional group tolerance has been developed using in situ activation of a bench-stable iron(II) pre-catalyst and pinacolborane (16 examples, 45-95% yield, TOF up to 30,000 mol h(-1)). The first iron-catalysed alkene hydrogermylation is also reported.

Abstract The study investigates hydrogenation of CO 2 over mono- and bimetallic catalysts supported on biochar. In this reaction, iron–cobalt were shown to surpass monometallic iron cobalt in terms catalytic performance. optimal combination performance parameters was reached at an ratio 3 : 1. composition genesis the active phase Fe–Co catalyst identified, mechanism suggested for iron-dominated...

Iron is essential to erythrocyte oxygen transport and is a catalyst for oxidative metabolism in all cells. Iron is absorbed by the duodenum and requires an acidic environment for optimal absorption. Iron is found for 70% in erythrocytes, and 30% in storage, and a small amount in myoglobin and cytochromes. Iron supplementation reduces anemia in breastfed infants and increases in significant dose...

Ammonia synthesis is the single most important chemical process in industry and has used the successful heterogeneous Haber-Bosch catalyst for over 100 years and requires processing under both high temperature (300-500 °C) and pressure (200-300 atm); thus, it has huge energy costs accounting for about 1-3% of human's energy consumption. Therefore, there has been a long and vigorous exploration ...

Currently, and looking forward, there is an ever increasing demand to perform chemical transformations with optimized atom and energy efficiency. In parallel, there is also growing interest in diversification of chemical feedstocks from more traditional ones. For example, effective and economic transformation of biorenewable chemical feedstocks and shale-gas, are just two that can be highlighte...

The iron-based catalyst was prepared by a microemulsion method. The composition of the final nanosized iron catalyst, in terms of the atomic ratio, contains 100Fe/4Cu/2K. The experimental techniques of XRD, BET, TEM, and TPR were used to study the phase, structure, and morphology of the catalyst. Fischer-Tropsch synthesis (FTS) reaction test was performed in a fixed bed reactor under pressure o...

The performance of Mo-enriched, bulk ferric molybdate, employed commercially for the industrially important reaction of the selective oxidation of methanol to formaldehyde, is limited by a low surface area, typically 5-8 m(2) g(-1). Recent advances in the understanding of the iron molybdate catalyst have focused on the study of MoOx@Fe2O3 (MoOx shell, Fe2O3 core) systems, where only a few overl...

Nano-sized iron-based catalyst was prepared by the micro-emulsion method. The composition of the final nano-sized iron catalyst, in term of the atomic ratio contains: 100Fe/4Cu/2Ce. Experimental techniques of XRD, BET, TEM and TPR were used to study the phase, structure and morphology of the catalyst. Fischer-Tropsch Synthesis (FTS) reaction test was performed in a fixed bed reactor at pressure...

N2O decomposition on iron-doped boron nitride nanotubes (Fe-BNNTs) was investigated by means of the density functional theory (M06-L). Two different forms of Fe-BNNTs, which are substitutions of the Fe atom into the boron-vacancy and nitrogen-vacancy sites of BNNTs, were used as the catalyst. Influence of the support plays a crucial role in the electronic configuration and catalytic reactivity ...
