Resumen

Los catalizadores de rutenio ahora pueden convertir el monóxido de carbono en productos multicarbónicos como el etileno y el ciclopropano, superando las limitaciones anteriores en la formación de enlaces C-C para la reducción de CO.

Área de la Ciencia:

Química organometálica
Catálisis
Química del carbono

Sus antecedentes:

Los complejos de rutenio como cis-[Ru(bpy) 2 ((CO) 2+ reducen el CO2 y el CO a productos C1.
La formación de enlaces C-C a partir del CO ha sido un desafío importante en la catálisis.

Objetivo del estudio:

Presentar una nueva vía de reacción para la conversión del monóxido de carbono (CO) en productos multicarbónicos.
Elucidar los intermediarios clave involucrados en la formación de enlaces C-C durante la conversión de CO.

Principales métodos:

Se utilizaron experimentos de captura con nitriles y piridina para caracterizar los intermedios clave.
Se empleó un análisis cristalográfico para determinar la estructura de un complejo de ylide.

Principales resultados:

Se identificó como un intermediario clave un complejo de rutenio metilideno, [Ru(bpy') 2 ((CO) ((CH2) 2+).
El etileno se generó a partir del complejo de metilideno a través de la protonólisis del precursor hidroximetilo.
Se ha demostrado la formación de enlaces C-C a través de la reacción del intermediario de metilideno con nitriles, piridina e incluso etileno, dando lugar al ciclopropano.

Benzene to 1,4-Cyclohexadiene: Birch Reduction Mechanism

Benzene to 1,4-Cyclohexadiene: Birch Reduction Mechanism

Birch reduction uses solvated electrons as reducing agents. The reaction converts benzene to 1,4-cyclohexadiene. The reaction proceeds by the transfer of a single electron to the ring to form a benzene radical anion. This anion is highly basic—it abstracts a proton from the alcohol to form a cyclohexadienyl radical. Another single electron transfer gives the cyclohexadienyl anion. A proton transfer from the alcohol forms 1,4-cyclohexadiene. Since this reduction occurs via radical anion...

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation

Introduction
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation

Catalytic hydrogenation of alkenes is a transition-metal catalyzed reduction of the double bond using molecular hydrogen to give alkanes. The mode of hydrogen addition follows syn stereochemistry.
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Reduction of Benzene to Cyclohexane: Catalytic Hydrogenation

Reduction of Benzene to Cyclohexane: Catalytic Hydrogenation

Unlike the easy catalytic hydrogenation of an alkene double bond, hydrogenation of a benzene double bond under similar reaction conditions does not take place easily. For example, in the reduction of stilbene, the benzene ring remains unaffected while the alkene bond gets reduced. Hydrogenation of an alkene double bond is exothermic and a favorable process. In contrast, to hydrogenate the first unsaturated bond of benzene, an energy input is needed; that is, the process is endothermic. This is...

Olefin Metathesis Polymerization: Overview

Olefin Metathesis Polymerization: Overview

Recently, the development of olefin metathesis polymerization advanced the field of polymer synthesis. Simply put, the reorganization of substituents on their double bonds between two olefins in the presence of a catalyst is known as the olefin metathesis reaction. The use of metathesis reaction for polymer synthesis is called olefin metathesis polymerization.
Ruthenium-based Grubbs catalyst is the most commonly used catalyst for olefin metathesis polymerization. Grubbs catalyst consists of a...

Cycloaddition Reactions: MO Requirements for Photochemical Activation

Some cycloaddition reactions are activated by heat, while others are initiated by light. For example, a [2 + 2] cycloaddition between two ethylene molecules occurs only in the presence of light. It is photochemically allowed but thermally forbidden.
