Organometallic Reactions Part 2: Oxidative Addition

The video tutorial explains oxidative addition, a key organometallic reaction where new ligands attach to a metal, altering its oxidation state. It covers the mechanism, including concerted and stepwise processes, and provides examples with metal complexes. The tutorial also discusses the complexity and variations in these reactions, highlighting the importance of electron count and potential stereoisomers.

What is a key characteristic of metals that commonly undergo oxidative addition?

• They have stable oxidation states that are two apart.

• They do not change oxidation states.

• They are always in the +3 oxidation state.

• They are only found in nonpolar environments.

In a concerted oxidative addition, how do the two groups typically end up?

• Trans to one another

• Cis to one another

• In a radical state

• Separated by a ligand

Which type of bonds are more likely to undergo stepwise oxidative addition?

• Metal-metal bonds

• Ionic bonds

• Nonpolar bonds

• Polar bonds

What happens to the oxidation state of a metal during stepwise oxidative addition?

• It decreases by 2.

• It remains unchanged.

• It increases by 2.

• It decreases by 1.

What is a potential outcome when oxidative addition involves multiple groups?

• Mixture of stereoisomers

• Creation of a radical

• Complete dissociation of the metal

• Formation of a single product

Which type of bonds are commonly involved in oxidative addition?

• Ionic bonds

• C-C bonds

• H-Si bonds

• Metal-metal bonds

Why can't D0 metals participate in oxidative addition?

• They have no d electrons to lose.

• They are too reactive.

• They are always in a +3 oxidation state.

• They form too many stereoisomers.
