oxidative addition

Then, the oxidative addition of a second silane unit occurs.

Oxidative addition requires that the metal complex have a vacant coordination site.

These reactions probably proceed via oxidative addition of the thiol.

In path a, the first step proceeds with the oxidative addition of the halogen to the metal complex.

Oxidative addition is a process that increases both the oxidation state and coordination number of a metal centre.

They are better able to provide electron density to promote hydrogen gas oxidative addition to the metal.

The addition of two one-electron ligands is called oxidative addition.

The reaction mechanism usually begins with oxidative addition of one organic halide to the catalyst.

Oxidative addition is favored for metals that are (i) basic and/or (ii) easily oxidized.

One-electron changes are also possible and in fact some oxidative addition reactions proceed via series of 1e changes.

For this reason, oxidative additions are common for four- and five-coordinate complexes.

Reductive elimination is the reverse of oxidative addition.

Oxidative addition is also needed in order for nucleophilic addition of an alkyl group to occur.

The first step is the oxidative addition of palladium to the halide 2 to form the organopalladium species 3.

Vaska's complex can undergo oxidative addition and is notable for its ability to bind to O reversibly.

Oxidative additions proceed via many pathways that depend on the metal center and the substrates.

An example of ionic oxidative addition is the addition of hydrochloric acid.

The oxidative addition initially forms the cis-palladium complex, which rapidly isomerizes to the trans-complex.

He discovered the main reactions of oxidative addition, a process that is central to homogeneous catalysis in organometallic chemistry.

A cycle of oxidative addition and reductive elimination on the copper center then creates a new carbon-carbon bond.

Complexation of a haloarene to chromium increases its propensity to undergo oxidative addition.

In contrast, a coordinatively saturated complex resists undergoing substitution and oxidative addition reactions.

A key step in hydrocyanation is the oxidative addition of hydrogen cyanide to low-valent metal complexes.

Oxidative addition also can occur to dimetallic complexes, e.g.:

Heck's contributions are not limited to the activation of halides by the oxidative addition of palladium.
